Adaptive Rate-Distortion Optimization for H.264

  title={Adaptive Rate-Distortion Optimization for H.264},
  author={Kwan-Jung Oh and Yo-Sung Ho},
In video coding standards, such as MPEG-4 and H.263, one important question is how to determine motion vectors for motion compensation in the INTER mode. Usually the sum of absolute differences (SAD) or the sum of squared differences (SSD) is employed as a matching criterion. Although these criteria are related to the distortion, they do not consider the bit rate appropriately. If we want to consider both the rate and the distortion, a Lagrangian technique targeting for rate-distortion… CONTINUE READING
