Corresponding dots of an autostereogram are assigned slightly differing colors (rather small changes in the hue value). The brain still superimposes these dots while the color dependency of corresponding dots is somewhat reduced.
Two depth scenes can be integrated into a single autostereogram. The final image is subdivided into rectangular regions (like a chessboard). One depth scene is represented in the "white" squares wheras the second scene is represented in the "black" squares.
Two autostereograms can be merged into a single autostereogram. Both autostereograms contain background and forground dots. The foreground dots of one autostereogram are, e.g., red, and are, e.g., blue for the second autostereogram. Merging is done pixel by pixel. Two background pixel produce a background pixel. A background pixel and a foreground pixel produce a foreground pixel. Two foreground pixel produce a foreground pixel. In this case the color is determined randomly. With this approach the scenes of the two individual autostereograms are perceived as being transparent.
