Toward Visualization and Searching: A Dual-Purpose Video Coding Framework

Wavelet Interlaced Video Coding Framework

A Discrete Wavelet Transform (DWT) based codec with EBCOT/ adaptive coding mode switching/ low-band-shift (LBS) is presented in this paper. The adaptive coding mode switching is used for both intraand inter-frame coding, respectively, to improve the rate vs. distortion (R-D) performance. EBCOT, the coding engine used in JPEG2000 is adopted in this framework because of its embedded R-D optimizat...

A Video Coding Framework with Spatial Scalability

A new video coding paradigm, distributed video coding, has been the focus of many recent studies. In this paper we present a simple video coding framework, based on the principles of distributed coding, that can be applied to any video coding standards with minor modifications. The framework allows spatial scalability of the non-reference frames, and does not need any feedback channel between t...

Texture refinement framework for improved video coding

H.264/AVC standard offers an efficient way of reducing the noticeable artefacts of former video coding schemes, but it can be perfectible for the coding of detailed texture areas. This paper presents a conceptual coding framework, utilizing visual perception redundancy, which aims at improving both bit-rate and quality on textured areas. The approach is generic and can be integrated into usual ...
