An apparatus and method is provided for the automatic real-time, bi-layer segmentation of foreground and background portions of an image using the color and infrared images of the image. The method includes illuminating an object with infrared and visible light to produce infrared and color images of the object. An infrared mask is produced from the infrared image to predict the foreground and background portions of the image. A pentamap is produced from the color image to define the color image into five distinct regions. An iterative relaxation-labeling algorithm is applied to the images to determine the foreground and background portions of the image. The algorithm converges when a compatibility coefficient between adjacent pixels in the image reaches a predetermined threshold. A Gaussian filter or matting technique can then be applied to smooth the transition between the foreground and background portions of the image.
