UK Research Now Featured on the ResearchChannel
University of Kentucky research is now reaching more than 22 million U.S. households, thanks to the ResearchChannel, a nonprofit media and technology organization that connects UK investigators with a global audience through cable and satellite distribution. Viewers can also tap into UK research projects through live web streaming and a video-on-demand library that is available 24-hours a day, seven days a week at www.researchchannel.org.
Several scientists in UK’s Center for Visualization and Virtual Environments have been featured recently, including Ruigang Yang, an assistant professor of computer science, and Samson Cheung, an assistant professor of electrical and computer engineering.
Yang’s project deals with a new approach to 3-D reconstruction in a visual display that he calls a “Light Portal.” In general, this portal will create a 3-D display that does not require the use of 3-D glasses. In order to create multiple angles, Yang uses an array of cameras to capture an object.
Video surveillance for security purposes is the focus of Cheung’s work. He has created programs that can manipulate video surveillance all the way down to the pixel level. For example, if such a video is being used in a court case, bystanders can be “erased.” But these images can be easily retrieved from the video if necessary because images are embedded into a secure watermark.
