Abstract :
A novel motion estimation/compensation scheme for full-motion interframe video compression is proposed. This scheme is based on prediction of interblock motion information by using minimum absolute difference block matching and hence substantially increases the searching and computation efficiency. A comparison is made with the `optimal´ full motion searching scheme for a standard test sequence. The experimental results show that the proposed scheme provides a computationally efficient algorithm in a real-time video communication environment
