ABSTRACT:
A method of enhancing a digital image that was transmitted with a reduced amount of digital data representing the digital image in which the differences between pixels in the digital image before compression are compared to corresponding pixels in a compressed version of the digital image and in which a statistical distribution of the differences is evaluated to determine which of the differences should be corrected. A receiver identifies portions of a received digital image that are to be enhanced, and a transmitter forms an error image for the identified portions. The amount of digital data in the error image may be reduced by selecting for transmission parts of the error image in which the amount of digital data that is needed to enhance the received digital image is less than a predetermined number of bits, the predetermined number of bits being selected from the distribution of the differences so as to enhance at least a predetermined percentage of the received digital image. Portions of the received image may be enhanced to have zero image loss.
