Lossless video compression using combination of temporal and spatial prediction

In this paper, we suggested a method for lossless video compression using combination of temporal and spatial adaptive prediction. This video encoder uses movement estimation to remove the temporal redundancy and uses GAP to remove the spatial redundancy, and then an adaptive method is used to combine the two predictions. The proposed schemes also use context-based coding. Experiment results shows that the proposed method has superior performance than state of the art lossless compression techniques JPEG-LS or CALIC about 10%, enabling more efficient video communications and storage.
