ABSTRACT:
In a method for separating a desired color region from a color image, color component values, which represent color components of the image, are calculated. Energy minimization is then carried out, in which calculations of an update rule for minimizing energy are iterated, in accordance with an energy function, which is defined by the color component values and a line process representing the presence or absence of continuity of the color component values in the image. A contour of the color region, which contour is represented by the line process and obtained from the energy minimization, is then extracted. The desired color region is thereby separated accurately from the color image without being affected by a background in the image.
