In this paper, we propose a coding algorithm for raw images with high dynamic ranges. Our encoder has two layers. In the first layer, 24 bit low dynamic range image is encoded by...
This paper addresses the problem of remote browsing of 3D scenes. Texture and geometry information are both available at server side in the form of scalably compressed images and ...

In this paper, we present a joint source-channel decoding technique based on exact MAP estimation for data encoded by CABAC (Context-based Adaptive Binary Arithmetic Coding) in st...
The implementation of a codec for real time applications such as video-conferencing at low bit rates is discussed. The discrete cosine transform has been used for compression, both...
Abstract— This paper discusses encryption operations that selectively encrypt content-carrying segments of multimedia data stream. We propose and analyze three techniques that wo...
