Video compression coding/decoding system and method based on underdetermined blind signal separation

The invention discloses a video compression coding/decoding system and method based on underdetermined blind signal separation, relating to the multimedia field. The method comprises the following steps: at a video transmitting end, carrying out hybrid processing on an original video according to an underdetermined blind signal separation algorithm; compressing and coding the video subjected to the hybrid processing; at a video receiving end, decompressing and decoding the received video; and carrying out separation processing on the decompressed and decoded video according to the underdetermined blind signal separation algorithm, thus obtaining the original video. By being combined with the traditional compression method, the video compression coding/decoding system and method based on underdetermined blind signal separation can achieve the purpose of further compressing the video, and can not cause intolerant distortion to the quality of the video. Besides, the method and system areextremely applicable to the video monitoring field.
