The transmitting end of the image coding system is basically composed of two parts. Firstly, performing decorrelation processing on an original digital image subjected to high-precision analog-digital conversion to remove redundancy of information; the decorrelated signal is then encoded, i.e. re-encoded, according to certain allowable distortion requirements.
