Claim One:
1. A method of determining a Q-value that indicates the blockiness level of an input image, comprising: receiving an input image comprising a plurality of pixels; receiving a binary block map that corresponds to an input image, the binary block map having indicators corresponding to each of the plurality of pixels in the input image, each indicator signaling if a block edge is present at the corresponding pixel location in the input image; receiving block locations indicative of the block edge locations in the input image; for each considered pixel, in a selected area of the input image, that is aligned to a block edge location and having an indicator signaling the presence of a block edge, calculating a flatness measurement indicative of the flatness of the pixel values adjacent to said each considered pixel; averaging the calculated flatness measurements to determine a Q-value, the Q-value indicative of the blockiness level of the input image selected area; and providing the Q-value for deblocking the input image.
