Baras, Gu, Jiang awarded patent for video codec

Professor John S. Baras (ECE/ISR) and ISR alumni Junfeng Gu and Yimin Jiang were issued U.S. Patent 7,006568 on Feb. 28, 2006 for 3D Wavelet-Based Video Codec with Human Perceptual Model,” a video encoding/decoding system.

The system applies JND (Just Noticable Difference) measurement in quantizer design to improve the subjective quality of compressed video. The 3D wavelet decomposition helps to remove spatial and temporal redundancy and provides scalability of video quality. This scheme simplifies the conditional access sub-system and provides system reliability.
