Embodiment Construction
[0051] Embodiments of the present invention are described in further detail below in conjunction with the accompanying drawings:
[0052] A distributed video encoding and decoding method based on CNM key frame classification, including a distributed video encoding method based on CNM key frame classification at an encoding end and a distributed video decoding method based on CNM key frame classification at a decoding end. The distributed video coding method based on CNM key frames at the encoding end can be used to improve the quality of distributed video coding side information; the distributed video decoding method based on CNM key frame classification at the decoding end adopts adaptive three-dimensional recursive search algorithm (A3DRS) and automatic Adaptive Overlapping Block Motion Compensation Algorithm (AOBMC), used to obtain more accurate motion vectors. The invention can effectively improve the overall rate-distortion performance of distributed video coding through ...
