ABSTRACT:
A method for detecting a contour of a given subject to be separated from images utilizing an image separating system. First, a plurality of candidate points which have been input by a user are displayed on a screen. A smooth curve which connects the plurality of candidate points is determined and is displayed on a display apparatus. The intensity of light on a straight line extending in a direction normal to each candidate point is determined. The position of the candidate point is corrected based upon the rate of change in the intensity of light which is determined for each candidate point. A smooth curve which passes the corrected candidate points is determined and is displayed on the display apparatus. The specified image, represented by the smooth curve connecting the corrected candidate points, is then separated from the rest of the image elements.
