We have made contributions to many aspects of image and video compression. Recently we have focused on predictive schemes.
Members: John Robinson, Matt Day
We are one of the few groups worldwide researching "pure" predictive coding of images and video (that is, where predictions are made pixel-by-pixel without an initial block or sub-band transform). Predictive coding adapts well to image type and compression requirements, which allowed us to develop first Binary Tree Predictive Coding (BTPC) then Adaptive Prediction Trees (APT) as high-performance general-purpose still-image compression schemes. Video and 3D versions of these coding schemes have also been developed.
