ABSTRACT:
The border of object in an image is blurred and so the modulation transfer function (MTF) of an image is reduced due to the blurred border. This present invention provides a deductive method for determining a border of an object in an image. Then the border of the object therein is amended and so the MTF of image is increased. In regard to an increasingly changeable color image, the present invention provides a deductive method in deciding upon a gray scale of the image to increase the color accuracy in amending an image.
