Abstract
A simple yet effective image sequence coding technique based on the zero-tree method is studied. The frames of the image sequence are decomposed hierarchically into 5 levels and motion compensation is performed on each subband separately. The displaced frame difference (DFD) is then encoded using the zero-tree method. Simulations done on the first 60 frames of the Miss America sequence using backward motion compensation with pel recursive motion estimation technique have yielded an average PSNR of 40.52 dB at a rate of 0.3 bpp and 43.68 dB at 1.0 bpp. This technique has the advantage that it works well with most images as no training set is required. There is precise control of the coding rate and the transmission is progressive.
