Claim:
1. A computer-implemented method to determine a feature mask for an image, the method comprising: estimating one or more prior regions in the image, wherein the one or more prior regions approximately define a feature in the image; determining a plurality of superpixels, wherein each superpixel is based on multiple pixels of the image that are similar in color; constructing a graph, wherein each node of the graph corresponds to a superpixel of the plurality of superpixels; determining a superpixel score associated with each of the plurality of superpixels, wherein the superpixel score is based at least on a number of pixels from which the associated superpixel is determined; determining one or more segmented regions in the image based on applying a graph cut technique to the graph based at least on the superpixel scores; determining the feature mask based on the one or more segmented regions, wherein the feature mask indicates a degree to which each of a plurality of pixels of the image depict the feature; and modifying the image based on the feature mask.
