Abstract
The invention provides a mechanism and process for changing a color of an image. In this process, a source frame that includes the image is received. An alpha matte that covers an object in the source frame is created. An original color of a pixel in the source frame is changed when the pixel is covered by the alpha matte, and when a color distance between the original color of the pixel and a target color is below a predetermined threshold.
