: In the process of transmission of digital encoded video bit streams over physical network, the data is corrupted by random bit errors, which has a several effect on the decoded v...
— An image sensor with focal plane based hardware acceleration of video compression is presented. The 90×90 pixel CMOS image sensor provides in-pixel processing of intensity cha...

In this paper we propose a compressed-domain image enhancement algorithm based on color appearance modeling. We aim at providing an efficient high-quality JPEG color image enhancem...
In this paper, we propose a system-level error tolerance scheme for systems where a linear transform is combined with quantization. These are key components in multimedia compress...
A transform approximation is explored for speeding up the software compression of images and video. It is used to replace the regular DCT whenever only few DCT coefficients are ac...
