ABSTRACT:
Light distortion due to light noise or light scattering object in the path of a light beam from a projector to a camera's image sensor in projector-camera systems are mitigated, or eliminated, by a simple modification to a light transport matrix T. For each row in light transport matrix T, matrix entries along a common row are compared, and all but the highest valued entry in the row are zeroed out, i.e. nullified. It is preferred that an array and record notation be used in order to reduce the size of the light transport matrix T, and its modified version to two arrays.
