A technique, and associated system and computer executable program code on a computer readable storage medium, for automatically correcting distortion of a front-projected display under observation by at least one camera. The technique may be employed in a myriad of front-projected display environments, e.g., single or multiple projectors and cameras are used. The technique includes: observing a first image, projected from at least one projector, comprising at least one target distribution of light intensities; for each conglomeration of white pixels of a difference image, compute a bounding box comprising a corresponding conglomeration of pixels in a framebuffer information of the …
