A modified optical flow algorithm (MOFA) is proposed for the development of a very low bit-rate video coding system. Another edge preserving constraint and pyramid approach are suggested to generate an accurate motion field and reduce the possibility of being trapped in a local minimum. Post-processing schemes are also designed to eliminated the problems for special regions. Compared with other motion estimation algorithms, the proposed method gives a more exact estimation in terms of the PSNR and subjective view. The arbitrarily shaped transform of the motion field is then selected to further remove the spatial redundancy. According to some primary simulation results, most of the test sequences are compressed into 16 kbps or lower with excellent picture quality
