摘要： An input frame to be motion compensated is partitioned into smaller blocks of pixel data. First, motion estimation is performed on each block in full-pixel resolution. Then, full-pixel resolution motion vector is refined to half-pixel accuracy by searching the surrounding half-pixel resolution blocks in vertical and horizontal positions with respect to the full-pixel resolution motion vector. An absolute magnitude of a horizontal component of the full-pixel resolution motion vector is examined to see if it is greater or less than a predetermined threshold to detect any significant movement. If the horizontal component absolute magnitude is less than the threshold, a frame-based interpolation will be used for forming the sub-pixel resolution block. If the horizontal component absolute magnitude is greater than the threshold, a field-based interpolation will be used instead. The sub-pixel resolution block is subjected to motion estimation and compensation to obtain a predicted block which will then be coded to obtain a coded bit stream.

摘要： A macro-block (MB) quantization reactivity compensation method for a video encoder is provided. The method calculates a reference picture quantization value based on a calculated picture complexity.
