Abstract
An adaptive scan method for image/video coding in accordance with the present invention comprises acts of calculating an average power of the transformed coefficients vector and acts rearranging the powers of the transformed coefficients with descending order in the data block according to the power of transformed coefficients; Therefore, the adaptive scan method is dependent on different prediction mode witch has been coded in H.264 standard, and provides better rate-distortion performance in entropy coding to the conventional zig-zag scan.
