AbstractIn this paper, a method to determine the visibility thresholds for a given subband system is introduced. Our approach identifies the important worse case combination of the quantization error in each basis function and determine the corresponding visibility thresholds using results previously measured in the DCT domain. Using the proposed method, it is relatively simple to determine the visibility thresholds for any subband system in the YCrCb domain. Simulation results on the Lapped Orthogonal Transform (LOT) show that the visibility thresholds are useful in visually lossless coding and perceptual weighted quantization.
