Very low bit rate video coding using matching pursuits
The term matching pursuits refers to a greedy algorithm which matches signal structures to a large, diverse dictionary of functions. The technique was proposed by Mallat and Zhang 1 with an application to signal analysis. In this paper, we show how matching pursuits can be used to e ectively code the motion residual in a hybrid video coding system at bit rates below 20 kbit/s. One advantage of ...
متن کاملGain-shape optimized dictionary for matching pursuit video coding
We show that the vector quantizer (VQ) techniques can be used to optimize a matching pursuit dictionary and improve the PSNR performance at low bitrates. The basis functions are the shape part, and the inner product values are the gain part of the VQ. The performance is evaluated based on a comparison of the PSNR in encoding motion residuals obtained using a matching pursuit coder with a refere...

Matching pursuits is a dictionary-based coding method, which has recently been demonstrated to outperform standard techniques, such as H.263, at low bit rate video compression. Unfortunately, the method involves an extremely high computational cost, compared to the DCT-based H.263. The contribution of this paper relies on reporting three new dictionaries for matching pursuits video coding, whos...
متن کاملMatching pursuits video coding: Dictionaries and fast implementation
Matching pursuits over a basis of separable Gabor functions has been demonstrated to outperform DCT methods for displaced frame difference coding for video compression. Unfortunately, apart from very low bit-rate applications, the algorithm involves an extremely high computational load. This paper contains original contribution to the issues of dictionary selection and fast implementation for m...
متن کاملContent-based and perceptual bit-allocation using matching pursuits
When communicating at a very-low bit-rate, video coders are unable to preserve high visual quality for all images. A selection of key regions according to human viewing and understanding may therefore be useful: it allows extracting essential features and to code them with a high quality, while the remainder of the image is coarsely transmitted. Such an approach requires a signal decomposition ...
