Abstract
A system and method for color enhancing an image or a series of images such as a motion picture by digitally capturing the images, interactively defining masks corresponding to objects in the images having similar hues, creating regions from these masks, and for each region, defining a color transfer function for converting image gray-scale information to unique values of Hue, Luminance, and Saturation. The gray-scale values within each region are then processed through that region's color transfer function, and the resulting colors applied to the image and stored for later retrieval and display.
