Side information generation based on pixel level motion vector field
|
Abstract:
The quality of side information generated by a decoder has a significant influence on the Rate-Distortion(RD) performance of distributed video coding(DVC) codec.In order to improve the RD performance of a DVC by improving the quality of side information,a new side information generation algorithm based on pixel level motion vector field(SGPMVF) is proposed.First,the accurate pixel level motion vector fields(PMVF) of the forward and backward key frames are acquired respectively by motion estimation;then,the ...
