Abstract
A system and a method for correcting chromatic aberrations of a color image composed of a plurality of digitized color planes. The color image is assumed to have been produced by an optical system. According to the system and method, geometric anomalies of the digitized color planes are modeled and corrected, at least partly, in such a way to obtain corrected digitized color planes. The corrected digitized color planes are then combined to obtain a color image corrected completely or partly for the chromatic aberrations. The system and method are applicable to photographic or video image processing, in optical devices, industrial controls, robotics, metrology, etc.
