SYSTEM AND METHOD OF CONVERTING HUE OF FLAT AND THREE-DIMENSIONAL IMAGES

摘要

FIELD: information technology.SUBSTANCE: method involves selecting a hue conversion function based on analysis of distribution of hue of elements of the entire image, varying parameters of the hue conversion function for each image element based on analysis of said distribution of the local surrounding region, where parameters are varied gradually for neighbouring image elements; and converting hue of each image element using the hue conversion function with parameters obtained for that image element.EFFECT: high quality of digital images by increasing global and local contrast without generating undesirable artefacts and distortions.12 cl, 8 dwg
