Paper Abstract

A very low bit-rate video coding algorithm is proposed. The algorithm is a hybrid motion compensation and DCT (discrete cosine transform) coding. However a progressive transmission scheme with a frequency-oriented coding of DCT coefficients is proposed to cope with partial freeze due to the buffer overflow. In addition, some methods to improve motion estimation are proposed. The simulation results show the proposed algorithm shows perceptually better decoded images than the traditional RM8 (reference model 8) algorithm.
