| Abstract | In this paper we present an image compression technique which employs classified vector quantization and mean prediction. We describe a perceptual block classification algorithm with reduced computational complexity which determines the class for each image block. The block is then encoded with a vector quantization and mean prediction. We described a perceptual block classification algorithm with reduced computational complexity which determines the class for each image block. The block is then encoded with a vector quantizer designed specifically for that class. Mean prediction is used to improve the performance of smooth areas of the image at low bit rates. In this case a residual vector quantizer is employed. Run-length coding are used to reduce the bit rate required to encode the side information. |
