Abstract:
1. A method comprising: receiving an image having at least one object; generating, by a computing device, at least two scale space images from the image, the computing device comprising a processor configured to cause the computing device to create the at least two scale space images, the at least two scale space images having different levels of detail and being the same size; using the at least two scale space images to determine, for each pixel of the image, a three-dimensional graph with a plurality of links to adjacent pixels to that pixel; determining a plurality of weights for the plurality of links of the three-dimensional graph; determining potential values from the plurality of weights, each potential value representing a likelihood of an associated pixel being within a boundary of the object or being outside the boundary of the object; determining a potential map from the potential values; and using the potential map to process the image.
