FASVQ: a feasible vector quantization architecture

Image encoding using a new high-speed and high-quality FASVQ (filtering and seeking vector quantization) architecture is proposed. The FASVQ coding scheme consists of three phases. The first and the second phases look like a filter which prune away those codevectors with larger distortions through a single cost estimation function. The third selects exhaustively the minimum distortion codevector within a fixed number of candidates suggested in the first and the second phases. This architecture can realize an environment with a frame rate of thirty 512×512 YUV (4:1:1) color image frames per second. The results of simulation for this coding scheme are presented
