IDENTIFYING BANDING IN DIGITAL IMAGES

摘要

One or more implementations access (100) a digital image and determine (105) whether at least one portion of the digital image includes one or more bands having a difference in color. The determination is based on at least two candidate scales. One or more implementations access (150) a digital image and assess (155) at least a portion of the digital image for the existence of one or more bands having a difference in color. The assessing includes determining a fraction of pixels in the portion having a color value offset by an offset value from a color value of a particular pixel in the portion.
