We propose a method for texture replacement in video sequences. Our method, which is applied at the encoder side, consists of removal of texture from selected regions of the original frames, synthesis of new texture, and mapping of the new texture ba

The challenge of multimedia processing is to provide services that seamlessly integrate text, sound, image, and video information and to do it in a way that preserves the ease of use and interactivity of conventional plain old telephone service (POTS

We propose a scheme for coding subregions in video scenes to provide content-based scalable video. For each region, a special color is used to represent the nonobject area, and the resulting frames are coded using conventional video coding algorithms

Constraints on the encoded bit rate of a video signal that are imposed by a channel and encoder and decoder buffers are considered. Conditions that ensure that the video encoder and decoder buffers do not overflow or underflow when the channel can tr

State-of-art encoders in real life applications typically select the number of B frames to be coded between each I or P frame to be equal to one or two by default. The few research works that have addressed the problem of encoder optimization by fram

Identifying pans and zooms in video sequences allows parameter switching for more effective encoding in standards such as H.264, and retrieval of documentary movies in video databases. In this work we propose a simple yet effective look-ahead method
