 | PhotoTechEDU Day 32 - Art, Science and Reality of High Dynamic Range (HDR) Im... Google Tech Talks January, 25 2008 ABSTRACT High Dynamic Range (HDR) image capture and display has become an important engineering topic. The discipline of reproducing scenes with a high range of luminances has a five-century history that includes painting, photography, electronic imaging and image processing. HDR images are superior to conventional images. There are two fundamental scientific issues that control HDR image capture and reproduction. The first is the range of information that can be measured using different techniques. The second is the range of image information that can be utilized by humans. Optical veiling glare severely limits the range of luminance that can be captured and seen. In recent experiments, we measured camera and human responses to calibrated HDR test targets. We calibrated a 4.3-log-unit test target, with minimal and maximal glare from a changeable surround. Glare is an uncontrolled spread of an image-dependent fraction of scene luminance in cameras and in the eye. We use this standard test target to measure the range of luminances that can be captured on a camera's image plane. Further, we measure the appearance of these test luminance patches. It is the improved quantization of digital data and the preservation of the scene's spatial information that cause the improvement in quality in HDR reproductions. HDR is better than conventional imaging, despite the fact the multiple- exposure-HDR reproduction of luminance is inaccurate. This talk describes the history of HDR image processing techniques including painting, photography, and electronic image processing (analog and digital) over the past 40 years. It reviews the development of Retinex theory, and other spatial-image- processing algorithms, that calculate appearance in images from arrays of radiances. Speaker: John McCann John McCann received a B.A. degree in Biology from Harvard University in 1964. He worked in, and later managed, the Vision Research Laboratory at Polaroid from 1961 to 1996. He has studied human color vision, digital image processing, large format instant photography and the reproduction of fine art. He is a Fellow of IS&T. He is a past President of IS&T and the Artists Foundation, Boston. He is currently consulting and continuing his research on color vision. He is the IS&T/OSA 2002 Edwin H. Land Medalist and IS&T 2005 Honorary Member and will be a 2008 Fellow of the Optical Society of America. |
 | The Great Breakthroughs in 20th-Century Science Physicist and novelist Alan Lightman chronicles the extraordinary saga of 20th-century science.

 | Richard Dawkins on the strangeness of science: TEDTalks http://www.ted.com Mind-expanding talk that probes the limits of human understanding: Why can't we see atoms? Why can't we hear color? How can we understand randomness? Dawkins suggests that the true nature of the universe eludes us because the human mind has evolved mainly to understand other humans -- and to look for human motives even in natural processes. Thus, we create a humanlike God to explain phenomena we can't otherwise comprehend; right or wrong, we're simply wired for it. Dawkins is Oxford's Professor for the Public Understanding of Science, and the author of the landmark 1976 book The Selfish Gene and the 2006 bestseller The God Delusion.

 | Jeff Hawkins: Brain science is about to fundamentally chang http://www.ted.com To date, there hasn't been an overarching theory of how the human brain really works, Jeff Hawkins argues in this compelling talk. That's because we still haven't defined intelligence accurately. But one thing's for sure, he says: The brain isn't like a powerful computer processor. It's more like a memory system that records everything we experience and helps us predict, intelligently, what will happen next. Bringing this new brain science to computer devices will enable powerful new applications -- and it will happen sooner than you think. |

 | A New Way to look at Networking Google Tech Talks August 30, 2006 Van Jacobson is a Research Fellow at PARC. Prior to that he was Chief Scientist and co-founder of Packet Design. Prior to that he was Chief Scientist at Cisco. Prior to that he was head of the Network Research group at Lawrence Berkeley National Laboratory. He's been studying networking since 1969. He still hopes that someday something will start to make sense. ABSTRACT Today's research community congratulates itself for the success of the internet and passionately argues whether circuits or datagrams are the One True Way. Meanwhile the list of unsolved problems grows. Security, mobility, ubiquitous computing, wireless, autonomous sensors, content... |
