Shape compensation is proposed in this paper to replace the DCT residue coding used in standard video coding. That is, our binary images are coded by the motion vectors and the class of morphological filters. Therefore the very low bit rate 1k bps can be easily achieved for the image size 64*64. Our coding procedures are simple: reducing quantization after reducing resolution, and shape compensation after motion compensation. However, the visual quality can be tolerable considering the carrying convenience ofthe small display and the inexpensive pay rate of communication. Therefore, the proposed coding strategy is suitable for video coding for ubiquitous services.
