In this paper, we investigate the problem of segmenting the foreground objects from the known background. The target application is a setting where a large display serves as the backdrop for a scene. The method proposed in this paper solves this problem in two steps. We try to separate the foreground and the background with the modified background subtraction base technique, which involves taking the per-pixel difference of the image with and without the foreground. The modification includes blurring the image before taking the difference and finding contours to separate noise and small objects in the background from the foreground. If the background subtraction fails, the chroma-key method is used: we put the solid colour screen behind the foreground object to ease the separation. To minimize the adverse effects of the chroma-key on the lighting of the objects, we propose the method for the background screen minimization using the pinhole camera theory.
