Image Defocus Simulator : A Software Tool 1 User ' s

Image Defocus Simulator (IDS) is an interactive research software tool developed to simulate the image sensing/formation process in a typical CCD camera system. IDS takes as input the camera parameters and the scene parameters. It produces as output a digital image of the scene as sensed by the camera. IDS consists of a number of distinct modules each implementing one step in the computational model proposed in our previous work. The modular design of IDS also make it portable to almost any machine with a C compiler in it. IDS was created to give the researcher in the eld of computer vision or image processing a exible, interactive, and user-friendly environment in which he/she can analyze and/or synthesize images without putting too much eeort in building the hardware equipments and/or setting up a laboratory. IDS will help in the veriication of computer vision theories.
