WebImplementation - Explanation. Here, we use a Bayesian Framework in order to achieve the problem of Natural Image Matting. The Image matting equation says that the observed colour is a linear combination of the foreground and background colors, weighted by a and 1 - a respectively, where a is a opacity matte that is unique for each pixel in the image. WebAbstract. This paper presents a method for automatically extracting a scene depth map and the alpha matte of a foreground object by capturing a scene through RGB color filters placed in the camera lens aperture. By dividing the aperture into three regions through which only light in one of the RGB color bands can pass, we can acquir three ... chinkeriches flowers photosWebmeaningful to combine depth map with image matting for the joint work.
