ADAPTIVE INTERFRAME WAVELET VIDEO CODING METHOD, COMPUTER READABLE RECORDING MEDIUM AND SYSTEM THEREFOR |
摘要 |
<p>An adaptive interframe wavelet video coding method, a computer readable recording medium and system therefor are provided. The interframe wavelet video coding method includes (a) receiving a group-of-frames including a plurality of frames and determining a mode flag according to a predetermined procedure using motion vectors of boundary pixels, (b) temporally decomposing the frames included in the group-of-frames in predetermined directions in accordance with the determined mode flag, and (c) performing spatial transform and quantization on the frames obtained by performing step (b), thereby generating a bitstream. Since an appropriate temporal filtering is performed in accordance with a boundary condition, efficiency of interframe wavelet video coding is increased.</p> |
