摘要

An apparatus and method to represent a video signal for improved source quality versus decoding complexity for a given compression rate and improved resistance against data loss when delivered over an error-prone network. The method comprises a 3-D matching pursuit algorithm with an improved 3-D dictionary. The 3-D MP encoder transforms blocks of frames into a set of spatio-temporal functions from the improved dictionary. The 3-D coder outputs a video stream that is highly resistant to data loss. Also, the proposed dictionary is optimized for source quality versus decoding complexity for a given compression rate.
