first_imgComputer users familiar with Photoshop and other image processing programs know that an image can be divided into “layers” for making color corrections, evening out contrast and enhancing details.  Your eyes do that, too, says Alan Gilchrist in Current Biology.1  He shows a stunning optical illusion to make the point: transparent chess pieces against differing cloudy backgrounds appear darker in one than the other, even though they are identical (see image and source paper by Anderson and Winawer in Nature.2)  Clearly, the brain is interpreting the pieces in relation to their context.    The rods and cones in your eye are not just light collectors that pass on signals direct to the brain.  Image processing is done before the brain gets the data (see 05/22/2003 entry).  Scientists are narrowing down theories for how this works.  Apparently, the rods and cones are not just sharing data with neighboring receptors, nor are they arranged into frameworks like states on a map.  The leading theory is that the eye decomposes the image into layers, and uses complex mathematical algorithms to “decompose” the combined image into its parts, including contrast, brightness, hue, illumination and saturation:For example, a red book on the dashboard of your car casts a red reflection in the windshield.  Through the reflection you perceive distant objects, including green grass, in their normal colors.  Light from the green grass and the red reflection physically mix to produce yellow.  The yellow is observed when seen through a small hole punched in a piece of cardboard held up so it blocks out the surrounding context.  Without the cardboard, however, no yellow is seen, only the red and green layers.  The brain is thought to split the yellow light into the red and green layers using rules that invert the usual rules of color mixing.  This is called scission.    Or consider the image of a white house reflected in the shiny surface of a black car.  Neither the house nor the car appears gray where their images overlap.  Rather the light at that location is perceptually split into a white and a black layer.    Strictly speaking, the illumination that falls on surfaces is not a separate layer.  But the same scission algorithms that work for transparent layers can be effectively applied to the illumination.  Mathematically a shadow and a sunglass lens have the same effect on the image.    When the processes of image formation are inverted in this way, surface reflectance is not merely computed, it is recovered.Does the fact that optical illusions can fool us (and fool everybody, systematically) mean that the “visual software employed by the brain” has bugs?  Not necessarily; “In principle, the errors could be accounted for by partial failures in the scission process,” Gilchrist says; ”But such efforts to model the errors have not proven very effective.”  Instead, the brain may combine the layer algorithm with a framework algorithm that is even more complicated.  Proponents of both theories are still trying to figure all this out.  “Both sides are open to an integration of the two approaches,” he says.  “Stay tuned.”1Alan L. Gilchrist, “Lightness Perception: Seeing One Color through Another,” Current Biology, Vol 15, R330-R332, 10 May 2005.2Anderson and Winawer, “Image segmentation and lightness perception,” Nature 34, 79-83 (3 March 2005) | doi: 10.1038/nature03271.Stay tuned: that implies we have limited ability to fathom such design.  Speaking of staying tuned, our ears do a similar kind of processing.  Students of advanced mathematics know that through Fourier Analysis and other techniques, one can separate out the individual contributors to a complex waveform.  For instance, your ear hears a hugely complex single waveform when listening to a symphony orchestra, but you are able to discern the individual sounds of the oboe, violin, trumpet, horn, timpani and all the rest.    It should be noted that our confusion with optical illusions should not cause us to infer errors in the code.  For one thing, our eyes were designed to operate in our natural habitat, not in the pages of books of optical illusions.  Second, the ability of humans to trick the software with illusions shows that humans have creative ability to alter a designed system and understand how it was tricked.  The algorithms of our image processing organs work for the environment for which they were designed.  They pull together the best responses to a vast array of possible inputs.  This is constrained optimization, the art of achieving the ideal compromise between competing inputs and priorities.    Gilchrist credits Johannes Kepler, one of the champion creation scientists in our online book, with discovering “that an image of whatever we look at is projected onto the rear inner surface of the eye,” just like in a camera obscura.  Ever since then, he says, “it has been natural to assume that the rods and cones function much as modern day photocells, reporting the point-by-point intensity of light in the image.”  Now we are realizing that the truth is far more amazing.  If Kepler’s discovery was marvelous to him, how much more should these recent discoveries make us stand in awe of the supreme optician of the universe?  (See also 05/09/2002 entry.)(Visited 9 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

first_imgJunior cross countrySouth Africa’s third medal came from Neethling in the junior cross country. Victory went to the talented 17-year-old Frenchwoman Pauline Ferrand-Prevot ahead of Switzerland’s Michelle Hediger. France’s Alexis Vuillermoz turned in the fastest last lap, but had to settle for second, a minute and 21 seconds behind Stander. Swiss rider Thomas Litscher grabbed the final podium position, two minutes and 46 seconds behind the South African. “Things worked out and I got into the track in second and from there on the race went perfectly,” Stander said. Greg Minnaar just missed out on winning the elite downhill title, while Candice Neethling picked up a bronze medal in the junior (under-19) women’s cross country. The biggest crowds of the event were in attendance at the downhill, which always produces spectacular racing. “Unfortunately we had a really strong head wind, so it wasn’t possible to take the lead from the beginning we had to take our chances in the group and then wait until the single track before we made a move. Head wind Minnaar just missed out on the title by only five-hundredths of a second to finish in the silver medal position, while Hannah stopped the clock in 2:31.02 to secure bronze. Runner-up finishesPeat had previously finished runner-up in 2000, 2001, 2002 and 2008 and so the victory meant a lot to the man who usually races with Minnaar as his team-mate for the Santa Cruz Syndicate. “It was pretty emotional putting the jersey on, on the podium knowing I could wear it as World Champion for the next year,” he said. “I’ve been trying for a long time and it’s just an unreal feeling.” Aggressive From the start, the man from Port Shepstone, KwaZulu-Natal went out aggressively to force open a lead over the rest of the field. He posted the fastest splits on each of the first five laps to take a convincing victory in one hour, 47 minutes and 26 seconds.center_img She said: “The start was extremely hard, I didn’t know what to expect and it is great just to get a medal.” Downhill victoryVictory went to 35-year-old Steve Peat of Great Britain, a legend in downhill racing who had amazingly never won the world title previously in his illustrious career. Riding fourth last in the field of 63 riders, Peat set a time of two minutes, 30.33 seconds. However, he had to then sit nervously and wait for home favourite Mick Hannah, World Cup overall champion Greg Minnaar, and defending world champion Gee Atherton to make their runs. The victory was a demonstration of Ferrand-Prevot’s versatility; in August she won silver in both the time trial and the road race at the UCI Junior Road World Championships in Moscow. 8 September 2009 Looking back on her effort, Neethling described the race as “extremely difficult, very technical.” Stander was a hot favourite to win the under-23 cross country title, deservedly so, as he entered the World Championships ranked fourth in the world in the elite (open) standings. Reflecting on his win, Stander said: “A couple of days leading up to it (the race) was pretty nerve racking (but) today I was just focused on the start because I knew it would play a vital part in the race.” South African competitors won gold, silver and bronze at the 2009 UCI Mountain Bike World Championships in Australia, with Burry Stander being crowned world under-23 cross-country champion.

first_img19 May 2010With the kick-off of the 2010 Fifa World Cup™ fast approaching, South Africa is on track to issue free visas to ticket holders and to process the hundreds of thousands of visitors expected in the country next month.Addressing a committee on the country’s state of readiness for the World Cup in Cape Town this week, Home Affairs Minister Nkosazana Dlamini-Zuma said Fifa employees were being awarded visas, and that the department had already issued 3 500 World Cup-related work permits.She said free event visas would be awarded to those with World Cup tickets, while dedicated lanes would be set aside for those coming to the tournament. Priority treatment would also be given to Fifa delegations and teams.Branded lanes, volunteersSpecific branded lanes were in the process of being set up at Durban’s King Shaka in Durban, Cape Town International Airport and OR Tambo International Airport in Johannesburg.The department was also training volunteers to work at airports in assisting arriving visitors.While a new movement control technology system which was launched at OR Tambo International was being rolled out across the country, the department had also placed airline liaison officers at various airports for clearing passengers and would enable police to screen visitors before they arrived.“It means the bulk of the passengers we would know that they aren’t high risk by the time they arrive at our airports and therefore would be cleared much faster,” said Dlamini-Zuma, who added that the system was piloted, together with Egypt, at last year’s Confederations Cup.International hubsInternational airports in countries including Kenya, the Netherlands, Hong Kong, Germany, India and Dubai had been identified as hubs where the majority of passengers would be passing through on their way to the World Cup.Discussions had been concluded with Kenya, Nigeria, the Netherlands, India, Hong Kong, Germany and the UK and negotiations were under way with Dubai, she said.Dlamini-Zuma said the department was working with South African Airways (SAA) to screen passengers before they came to South Africa, but added that this process had been delayed by the volcanic ash cloud over Europe in recent weeks.She said this would give SAA an advantage in that it would be quicker to clear immigration if you were flying the national airline.Land border pointsAt land border points, joint clearances were being set up, so that those passing through border checkpoints will only have to wait in a single queue, rather than going through one queue on either side of the border, she said.She said one such point had already been set up at the Lebombo border post at the Mozambique-South Africa.Other co-location points would be set up at the Zimbabwe border at Beit Bridge, Maseru and Ficksburg at the Lesotho border, Oshoek at the Swaziland border and at Kopfontein at the Botswana border.The department was also looking at introducing a transit visa for those that resided in neighbouring countries that passed through South Africa.Source: BuaNewslast_img read more

first_imgTagsTransfersOpinionAbout the authorChris BeattieShare the loveHave your say Sack Solskjaer? Why dumping manager won’t change anything at Man Utdby Chris Beattie16 days agoSend to a friendShare the loveCOMMENT: Pick a manager… Allegri, Poch.. any manager. Would any manager be able to get a tune out of this lot at Manchester United…?With international week comes the sack talk. Partly due to the need to fill the vacuum left by a barren league programme. But also due to the growing belief inside boardrooms that the best time to remove a manager is during such a recess. A chance to regroup and allow the new man to get his feet under the table before the action resumes.They’re already at it in Italy. AC Milan dumping Marco Giampaolo on Tuesday – just three months into his job. And they won the weekend, never mind being beaten at Newcastle United.But should defeat at St James’ Park be the last straw for United and Ole Gunnar Solskjaer?Well, for many – including some United ‘exes’ – the answer is ‘yes’. With the headlines blazing and the place apparently leaking, it only appears a matter of time before the board admit they were wrong and send Solskjaer back to Norway.Max Allegri has picked up his English lessons again. Mauricio Pochettino is trying to engineer a way out of Tottenham. It’s all lining up. Ed Woodward can get rid of Solskjaer and replace him with someone more suited to the job. Or so they say…Because no matter who is in the dugout, they’ll still have to make do with what’s available to them. Sunday’s team on Tyneside was nothing like what Solskjaer had at his disposal on the opening day for that win over Chelsea. Three of the back four were missing: Aaron Wan-Bissaka, Victor Lindelof and Luke Shaw. Paul Pogba was also absent, as was Anthony Martial in attack. Essentially, injury has robbed Solskjaer of almost half his first-choice team. And while critics will argue ‘it’s a squad game’, it really isn’t when you’re undergoing an overhaul as Solskjaer is now driving through. With Romelu Lukaku and Alexis Sanchez now pulling on an Inter Milan shirt for a living, the attack may be paper thin, but long-term it was the right call to shuffle off both players. Indeed, Lukaku is already finding how things can quickly turn in Italy. His coach at Inter, Antonio Conte, having to defend a sluggish performance from the striker for their defeat to Juventus. It was Lukaku’s first big test since his move from United – and it ended with his manager explaining away a lethargic showing.Of course at United, Lukaku would be getting a game today. But that’s not the issue. Solskjaer, with the support of the board, wanted to go in a different direction. And crucially, that support remains.As mapped out here, the club’s top brass have recognised the predicament that has befallen their manager. If results had been the same with Solskjaer’s first-choice XI, then serious questions would be asked. But not today. Not with this reality.Instead, the discussion has been about what’s been put in place – and whether it’s working. And the consensus is positive. The youth policy is showing the right signs. The progress of Scott McTominay and the introduction of Axel Tuanzebe have both pleased management. As have the impact of their three summer signings, Daniel James, Harry Maguire and Wan-Bissaka. On what they’ve seen this season, no-one inside Carrington have doubts about any of these five not being long-term prospects for the club.Indeed, the only criticism, said in some jest, is that Maguire could be doing better by his manager at the other end of the pitch. Being more decisive with that chance at 1-0 at West Ham, along with a soft free header at Newcastle, and the spotlight wouldn’t be so acute on Solskjaer as it is today.But in the aftermath of that Toon defeat, there were some positives – if we care to consider the long-term.It was significant that the two leading voices to react to the loss were David de Gea and Marcus Rashford. Both fresh from committing themselves to new contracts, their reactions were of men who have bought into something. They were taking ownership. Not so much for the result, but something far bigger – the project. De Gea, particularly, spoke of someone determined for this plan to succeed – and well aware of his place inside it. Time will tell if a new leadership group is forming, but the signs are that De Gea and Rashford do have the stomach for this fight the club is in.And it is a fight. Results have the club spiraling. But there are reasons. Reasons the board have accepted. They know, given current circumstances, a change of manager would make little difference. last_img read more

On Monday, Deontae Cooper was the big story at Washington. The running back had been given clearance to practice by doctors and was on the field, grateful that fought back from two torn ACL injuries in his left knee.“I’m just ready to strap ’em on and go, ready to grind till the doctor tells me I can’t play,” Cooper said. “If I tear my ACL five more times, I’m going to keep going.”He was all smiles and not only were his teammates rooting for him, so was the entire Huskie community.Then Wednesday came, and as amazing as it might sound, but Cooper went down again, during a non-contact drill. This time, it was his right knee. Torn ACL. Again.And in that moment, heartbreak fell over the football program. And Huskie Nation.Washington coach Steve Sarkisian posted a statement on CoachSark.com, his online blog:““I am saddened and dismayed to report that Deontae Cooper has torn the ACL in his right knee while participating in a non-contact drill during practice. Deontae has done everything we have asked of him, and has been an example to his teammates with his hard work in the classroom, and the dedication he showed in returning from two previous ACL surgeries in his left knee. Our football program will do everything we can to support him in this tough time.”Tough time? Try incomprehensible time. Try no-way time. Try you’ve-got-to-be-kidding-me time.Cooper, a redshirt sophomore listed at 6-foot, 201 pounds, had not played in a game in two years. Now, remarkably, he’s sidelined again.On Monday, Cooper said he was optimistic about playing, but that he was taking it “ day by day. You never know. I don’t want to say anything. You never know what can happen. I want to stay positive but I don’t want to get hopes up.”If ever there was an athlete to hope for, it is Deontae Cooper. read more

Former Michigan defensive line coach Greg Mattison  has been named Ohio State’s new co-defensive coordinator along with Jeff Hafley. Credit: Courtesy of TNSHaving two coordinators for both the offense and the defense is not a revolutionary concept that newly named head coach Ryan Day brings to Ohio State. Chris Ash and Luke Fickell were co-defensive coordinators from 2014-15. Fickell and Greg Schiano split duties during the 2017 season. Even Day and Kevin Wilson were named as co-offensive coordinators prior to the start of the 2018 season. Day said two coordinators brings a diversity of opinion, bringing proficiency to different parts of either the offense or the defense. That is why he hired both Gary Mattison and Jeff Hafley as co-defensive coordinators for the 2019 season. “I like the expertise and experience that Jeff has in the secondary coupled with the expertise that Greg brings to the front seven,” Day said in a statement. Mattison is not a new name to the head coach Day is replacing. From 2005-07, Mattison served as the co-defensive coordinator, along with current South Florida head coach Charlie Strong, and defensive line coach in former Ohio State head coach Urban Meyer’s first three seasons at Florida. Primarily, Day said he wanted to bring in Mattison for his experience in the Big Ten. Leaving his position as the defensive line coach at Michigan under head coach Jim Harbaugh, Mattison has been with the Wolverines for 13 seasons, having previously served as their defensive coordinator from 1995-96 and from 2011-14. Mattison also brings NFL experience, serving as the linebackers coach for John Harbaugh and the Baltimore Ravens in 2008 and being promoted to defensive coordinator in 2009 and 2010, leading the No. 3 scoring defense in each of those seasons. Last season with Michigan, his defensive line limited opponents to average 3.7 yards per carry and opposing quarterbacks to complete 49.5 percent of passes attempted, No. 1 in the Big Ten. However, with Larry Johnson, who was named as the associate head coach under Day while also serving as the defensive line coach, Mattison’s specific position group has not yet been defined. While Mattison brings age to the coaching staff, a 69-year-old position coach with 47 years of coaching experience, Hafley, according to Day, is a “rising star” and “one of the best secondary coaches in the country.” “His NFL knowledge coaching the secondary is only going to enhance and improve what has become a marquee area for the Buckeyes,” Day said. After college stops with Pittsburgh and Rutgers, the latter of which was under Schiano, Hafley has been a defensive backs coach in the NFL since 2012 for the Tampa Bay Buccaneers, the Cleveland Browns and the San Francisco 49ers. He worked under Chip Kelly in 2016, who also had Day on staff as his quarterbacks coach. In 2017, he helped lead a 49ers secondary to the No. 11 pass defense in the league, allowing 233.2 passing yards per game after inheriting the No. 27 pass defense in the country heading into the previous year. Day’s coaching staff is beginning to take shape, bringing two new faces to Ohio State. But the idea of co-defensive coordinators, two coaches bringing expertise to the defense, remains. read more
