Abstract
In the existing inter-frame wavelet video coding techniques, the poorly matched pixels from adjacent frames are temporally filtered into the high-pass temporal frame in the same way as the good matches using motioncompensated prediction (MCP). This tends to result in high-energy blocks being introduced into the high-pass frame, which leads to less efficient spatial coding of the affected frames. We propose to use prediction from spatial neighbouring pixels for high-pass filtering of the poorly matched blocks, which results in a significantly improved performance at low bitrates with no loss at high bitrates.
