Dictionaries for matching pursuits video coding

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, whose advantages include both a reduced computational cost and improved PSNR performance, compared to dictionaries reported to date.
