Abstract: Systems, methods, and computer-readable storage media can be used to perform alpha-projection. One method may include receiving an image from a system storing one or more images. The method may further include alpha-projecting the received image to assign alpha channel values to the received image by projecting one or more pixels of the received image from an original color to a second color and setting alpha channel values for the one or more pixels by determining the alpha channel value that causes each second color alpha blended with a projection origin color to be the original color. The method may further include displaying the alpha-projected image as a foreground image over a background image.
