Hide two pictures in one image: the front shows on white, the inner on black. Also extracts existing mirage images.
How it works: each output pixel stores a gray level plus an alpha channel computed from the brightness of the two source images. On white, transparent areas turn light so the front image appears; on black, they turn dark and the alpha-weighted inner image appears. Pixels where the inner image is brighter than the front image saturate and may look off on white.
