Brief analysis of inter prediction in video coding

Inter prediction creates a prediction model from one or more previously encoded video frames or fields using block-based motion compensation. In this paper, we briefly analyze the inter prediction tools available in the Baseline profile of the h.264 coding standard. Important differences from earlier standards include the support for a range of block sizes (from 16×16 down to 4×4) and fine sub-sample motion vectors (quarter-sample resolution in the luma component).
