Paper Abstract

Recently, Han et. al. developed a method for visually lossless compression using JPEG2000. In this method, visibility thresholds (VTs) are experimentally measured and used during quantization to ensure that the errors introduced by quantization are below these thresholds. In this work, we extend the work of Han et. al. to visually lossy regime. We propose a framework where a series of experiments are conducted to measure Just-Noticeable-Differences using the quantization distortion model introduced by Han et. al. The resulting thresholds are incorporated into a JPEG2000 encoder to yield visually lossy, JPEG2000 Part 1 compliant codestreams.
