1. A method for processing an image comprising a plurality of pixels, the method comprising:
processing, by one or more computer devices, the image and generating a first trimap and a second trimap, each trimap segmenting each pixel of the image into either a foreground region, a background region or an unknown region;
generating a merged trimap by processing the first trimap and the second trimap according to a reconciliation algorithm;
processing, by the one or more computer devices, the merged trimap and image to yield an alpha matte, the alpha matte comprising an alpha value for at least each pixel in the unknown region;
generating a processed image by applying the alpha matte to the image to remove the background region therefrom; and
outputting the processed image.
