This paper proposes a fast motion estimation algorithm for MPEG-4 shape coding. The proposed algorithm is based on inherent properties of shape coding as well as shape information...
In network delivery of digital video, if the bandwidth required for a video is not available, the video has to be recoded at a reduced bit rate. It is highly desirable that the tr...
This paper describes a hierarchical image registration algorithm for affine motion recovery. The algorithm estimates the affine transformation parameters necessary to register any...
