Abstract
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. When used to superimpose hair styles, the system includes means for defining locations on the hair style image, means for defining locations on the head image, means for superimposing the hair style image on the head image so that the defined locations on the hair style image fit those on the head image; and means for altering the size of the hair style in horizontal and vertical directions without altering the fit of the defined locations on the hair style image to the defined locations on the head image. Preferably, in frontal images, both ears and the center of the hair line are used as the defined locations. In a side view, one ear and the center of the hair line are used as the defined locations.
