Abstract
A digital image processing method for automatically outlining a contour of a figure in a digital image, including: testing parameters of a region within the digital image according to a plurality of cascaded tests; determining whether the region contains characteristic features of the figure within the digital image; computing location parameters of the characteristic features in the region for the figure within the digital image; determining boundary parameters for the figure corresponding to the location parameters of the characteristic features in the region; computing an information map of the digital image; computing a set of indicative pixels for the contour of the figure; and automatically outlining the contour of the figure using the set of indicative pixels, the information map, and a contour outlining tool.
