Abstract
The communications system comprises an encoder for encoding an input image. The salient features of the image prioritized and encoded accordingly. A low bandwidth media for transmitting the encoded input image is used. A decoder is coupled to the encoder for receiving encoded information. The decoder is non-symmetrical to the encoder for decoding merely a part of the encoded input image with improved subjective/perception quality. Whereby a human operator can reach a determination via visual inspection regarding the input image.
