Outline of Final Research Achievements

We investigated low bit-rate images and/or videos coding algorithm to avoid congestion, which is useful in time of disaster. The results of study for three years are 1) optimal code book design and image coding, 2) saliency region extraction and coding, 3) a model of motion vector by optical flow and an autoregressive model, 4) global motion compensation to group motion vectors. In future study, it is necessary to develop effective streaming technology to implement the coding algorithms into mobile communication terminals.
