Abstract
A method for the enhancement of medical images for hardcopy prints comprising the steps of: obtaining a medical image in digital format; conducting a plurality of operations for Human Visual System (HVS)-based edge enhancement with each operation having a uniquely specified high frequency amplification function and range such that edges are more enhanced in the shadow region than in the highlight region; adjusting image tone scale, for reflection prints increase the contrast in the shadow region and decrease the contrast in the highlight region, and for transparency prints decrease the contrast in the shadow region and increase the contrast in the highlight region; sending the processed image to the output device for hardcopy prints.
