February 7, 2013, Electronic Imaging Conference, Burlingame, CA—Marti Hearst from UC Berkeley described the requirements for future search user interfaces for multimedia. The growing volume of non-text entries on the Web demands a different search UI. Many of the search principles for non-text search are highlighted in the website http://searchuserinterfaces.com/book/, which identifies the issues associated [...]
February 4, 2013, Electronic Imaging Conference, Burlingame, CA—Vikas Ramachandra from Qualcomm explained the requirements for making HDR images with mobile devices. There is a great need for editing iHDR work, but tools like PhotoShop are too heavy for mobile devices. HDR techniques use multiple images with different exposures to accomplish the High Dynamic Range. the [...]
February 4, 2013, Electronic Imaging Conference, Burlingame, CA—Aude Oliva from MIT described her work in identifying characteristics of memorable pictures. This work is becoming more important as the number of photos spreads across the Internet. The number of images continues to grow, and the social media are accelerating the trend. Some estimates are that 90 [...]
February 4, 2013, Electronic Imaging Conference, Burlingame, CA—Alexander Oberdorster from the Fraunhofer Institute of Optics stated the need for adaptive optics in a plenoptic camera. This concept seems counter-intuitive, since these types of cameras are supposed to allow changing focus and depth of field in post processing. The reason for the adaptation is the nature [...]
February 4, 2013, Electronic Imaging Conference, Burlingame, CA—Donald Hoffman from UC, Irvine asked the question “does evolution favor true perceptions?” in his keynote talk. Evolution has always moved to work around poor designs with fixes that work with the least energy. We now know that about half of the brain is involved with visual processing, [...]
February 4, 2013, Electronic Imaging Conference, Burlingame, CA—Thomas Bindre from Nik Software presented concepts for selective editing of images on touchscreen devices. The growth of smart mobile devices allows picture-taking capabilities anywhere, but the quality of most pictures is poor. Editing can be a global operation, where all pixels are changed with some parameter, or [...]
February 4, 2013, Electronic Imaging Conference, Burlingame, CA—Wes Bethel from Lawrence Berkeley Lab explained why high performance visual data analytics is both relevant and difficult. The onset of big data and the advances in computers make some areas easier, but the big problems still need a lot of technology to find solutions. Visualization has always [...]
January 24, 2012, SPIE, Electronic Imaging Conference, Burlingame, CA—William Freeman from the Massachusetts Institute of Technology talked about computational photography. Today’s digital cameras have only replaced the imaging system, using a semiconductor imager versus film. Most of the camera functions are still analog. In computational photography the user can modify any or all of the [...]
January 24, 2012, SPIE Electronic Imaging Conference, Burlingame, CA—two technical teams presented the issues and suggested solutions for cinematic to television conversion for good 3-D. The complementary talks described the basic technology and specific techniques for the conversion processes. Didier Doyen noted that the problems are due to the changes in size and viewing distance [...]
