MPEG-compatible motion compensation using background/foreground information
This paper presents a new approach to block-based motion vector estimation, called the background/foreground motion search (B/FS) algorithm. This algorithm separates the background and foreground content inside a block to determine the motion vector of the block. As a result, the motion-compensated frames can be subjectively close to the original image. Experimental results show that our approach provides a significant improvement in the subjective quality of motion-compensated frames as compared with traditional MSE/MAD-oriented block-based methods.
