Motion-compensated lossless video coding in the calic framework
Elias S. G. Carotti, Juan Carlos De Martin · 2006
In this paper we consider the problem of lossless compression of video sequences exploiting the temporal redundancy between subsequent frames. More specifically, we present a lossless video coding technique which extends interframe-CALlC by employing multi-frame motion compensation to first temporally decorrelate the video material, followed by context-based arithmetic coding of the residual data. To avoid the well known context-dilution problem, we perform context quantization. The proposed technique, called motion-CALIC, is shown to outperform competing methods such as interframe-CALIC and LOPT-3D up to 22.93% in terms of bitrate savings, while still maintaining manageable complexity
