Abstract: An image enhancement system and method includes means for superimposing a second image, such as a hair style image, over portions of a first image, such as an image of a person's face. The system or method further automatically marks locations along the boundary between the first and second images and automatically calls a graphic smoothing function in the vaccination of the marked locations, so the boundary between the images is automatically smoothed. Preferably, the smoothing function calculates a new color value for a given pixel in the vicinity of such a marked location in at least two smoothing steps, the first of which calculates the color value for each of a plurality of pixels adjacent to the given pixel by combining color values from pixels which are separated, respectively, from each of those plurality of pixels by a distance of more than one pixel. The second step calculates the new color value for the given pixel by combining the color value of each of the plurality of pixels.
