Abstract

In this paper, we present an interband version of CALIC (context-based adaptive lossless image codec), a lossless image coding technique. It is demonstrated that CALIC´s techniques of context-based modeling of images lend themselves easily to modeling of image sequences. The generalized interframe CALIC can exploit both interframe and intraframe statistical redundancies, and obtain significant compression gains over intraframe CALIC. The advantage of interframe CALIC is demonstrated by experimental results on different types of multispectral images
