Improved motion description coding using the list mapping motion description (LMMD)

A novel technique for motion description encoding is proposed. The method is based on a vector list and a mapping, each of which is losslessly encoded using variety of algorithms. Results show that in comparison to H.263, the best performing algorithms offer a significant reduction in the number of motion bits required, for motion fields with relatively few unique vectors. The bits saving are particularly important for low bit rate coding applications.
