INTRA PREDICTION MODE DECISION WITH REDUCED STORAGE |
摘要 |
<p>In general, techniques are described for reducing the space required to store rate distortion values when selecting from multiple, different prediction modes. A video coding device comprising a processor may perform the techniques. The processor may determine first and second sets of intra-prediction modes for a current block of video data. The first and second sets of intra-prediction modes may include less intra-prediction modes, collectively, than a total number of intra-prediction modes. The processor may compute an approximate cost for each intra-prediction mode included in the first and second sets of intra-prediction modes. The processor may store the approximate cost for each intra-prediction mode identified in the first and second sets of intra-prediction modes to a memory. The processor may perform intra-prediction to encode the current block using a mode identified in at least one of the first or second set.</p> |
