METHODS AND SYSTEMS FOR MIXED SPATIAL RESOLUTION VIDEO COMPRESSION
摘要
<p>An original full resolution frame is encoded, stored and reconstructed The opginal full resolution frame is then downsampled to render a reduced spatial resolution frame, and the resulting reduced resolution frame encoded, stored and reconstructed The reduced resolution frame is then upsampled and stored so a comparison of a charactepstic in the reconstructed full resolution frame with the charactepstic in the original full resolution frame to determine deviation of the reconstructed full resolution frame from the opginal full resolution frame Another comparison of the upsampled reconstructed spatial reduced resolution frame the onginal full resolution fram can be done to determine a deviation of the upsampled reconstructed spatial reduced resolution frame from the onginal full resolution frame with respect to a charactepstic Coded data corresponding to a frame with the lesser deviation from the onginal full resolution frame with respect to said charactepstic can then be output to a bitstream</p>
