| 摘要 |
The invention relates to a video encoding method provided for encoding each frame of a sequence of successive groups of frames. This method comprises for each successive current frame, itself subdivided into blocks, the steps of estimating a motion vector for each block, generating a predicted frame from these motion vectors, applying to a difference signal between the current frame and the last predicted frame a transformation and quantization sub-step, and coding the quantized coefficients thus obtained. A preprocessing step, applied to each successive current frame, computes for said frame a so- called content-change strength (CCS), used to define a modified structure of the successive groups of frames to be encoded. ® KIPO & WIPO 2007 |
