Abstract

Visibility thresholds play an important role in finding appropriate quantization step sizes in image and video compression systems. In this paper we present a new method of measuring visibility thresholds for quantization distortion in JPEG2000. A quantization distortion model for each subband is developed based on the statistical characteristics of wavelet coefficients and the dead-zone quantizer of JPEG2000. Thresholds obtained from these quantization distortion models are image-adaptive and ensure visually lossless coding with low computational burden.
