Improved interpolation of video compression frames |
摘要 |
A method and system for improving the image quality of one or more predicted frames in a video image compression system, where each frame comprises a plurality of pixels. A picture region or macroblock of certain types of frames can be encoded by reference to two or more referenceable frames. Such encoding includes determining at least one macroblock within a bidirectional predicted frame (B) using direct mode prediction based on motion vectors from two or more predicted frames (P), wherein at least one such motion vector is scaled by a frame scale fraction of less than zero or greater than one. |
