Abstract
Particular embodiments generally relate to video compression. In one embodiment, a store of reference frames is provided in memory. The reference frames may be classified based on a plurality of classifiers. The classifiers may correspond to features that are found in the reference frame. A frame to encode is then received. The frame is analyzed to determine features found in the frame. As macroblocks in the frame are encoded, a macroblock is analyzed to determine which feature may be included in the macroblock. The feature is used to determine a classifier, which is used to determine a subset of the reference frames. The subset is then searched to determine a reference frame for the macroblock.
