Three efficient rate allocation schemes for the MPEG-4 fine granular scalability (FGS) enhancement layer with constant quality are proposed in this paper. With the distortion measured using the mean squared error (MSE) or peak signal noise ratio (PSNR) metric, the rate-distortion (R-D) curve of the MPEG-4 FGS enhancement layer exhibits piecewise characteristics. For each piecewise region, a first-order or a second-order model is adopted to estimate the actual R-D curve. Based on these piecewisedoi:10.1109/icme.2004.1394148 fatcat:klyf6rlscfba7bfuj77nh2pgf4
