face recognition is the most important challenging in the research area of computer vision. Different type of illumination takes place from dim light condition to dark light condition. Two types of condition are there. a) Controlled condit

A camera raw image file contains minimally processed data the image sensor of either a digital camera, image scanner, or motion picture film scanner.Raw files are named so because they are not yet processed and therefore are not ready to be printed o
