Abstract： |
This invention relates to a binary-value method in the encoding of conversion coefficient entropy in image encoding, which designs a new binary-valued method to a series of factors after scanning the image block characterizing in first of all, encoding the last non-zero coefficient position information in a code stream then the last non-zero factor begins to carry out algorithm encoding to all factors in countdown sequence secondly, after the last non-zero factor is binary-valued, a probability model is selected to encode it. |
