A method, system, and computer-readable storage medium are disclosed for generating a location-weighted mask based on a color model comprising spatial dimensions. In one embodiment, a selection of at least one pixel in an input image is received, wherein the selection of the at least one pixel comprises a color and a location within the input image. A color model may be determined based on the color and the location of the at least one pixel, wherein the color model comprises one or more truncated Gaussian functions. A mask may be generated based on the color model. The mask may indicate a degree of membership in the mask for each pixel in the input image as a function of a similarity in color to the at least one pixel in the selection and a proximity to the location of the at least one pixel in the selection.
