An Improved Visual Pruning Algorithm for Perceptually Lossless Medical Image Coding

An improved algorithm for perceptually lossless coding of medical images is presented in this paper. Built on the JPEG 2000 coding framework, the proposed coder combines an improved visual pruning algorithm with an advanced model of the human visual system to identify and to remove visually insignificant/irrelevant information. Current results have shown superior compression ratio gains over that of its lossless counterparts without any loss in visual fidelity.
