Abstract
A semiautomatic drawing tool is configured to generate an image segmentation contour that corresponds to a visible edge within a digital image. Individual contour points define the shape and location of the image segmentation contour, and the semiautomatic drawing tool determines the locations of these contour points based on both user input and on the location of a steep luminance gradient that corresponds to the visible edge. The semiautomatic drawing tool determines the location of a particular point of the image segmentation contour based on the current location of an input device pointer, e.g., a cursor, the location of the steepest luminance gradient, and the location of previously selected points of the image segmentation contour.
