Reference pictures are selected for the sub-pixel motion estimation based on full-pixel motion estimation. A cost function is used to select the reference pictures from one or more groups of reference pictures for a block in a macroblock. The cost is based on full-pixel motion estimation errors and a predicted motion vector for the block. The selected reference pictures are used for sub-pixel motion estimation to get the final motion vector for each block."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Reference picture selection for sub-pixel motion estimation","description":"A video coding system includes a prediction module configured to perform multi-reference picture sub-pixel motion estimation.
