METHOD FOR CONVERTING A TWO-DIMENSIONAL DISTANCE FIELD TO A SET OF BOUNDARY DESCRIPTORS

摘要

A method converts a two-dimensional distance field to a set of boundary descriptors. An iso-contour of the two-dimensional distance field is selected. An ordered list of points is generated from the iso-contour and the two-dimensional distance field. A set of boundary descriptors is initialized to fit the ordered list of points. The set of boundary descriptors is updated by determining an error for each boundary descriptor using the two-dimensional distance field and refining the set of boundary descriptors based on the error for each boundary descriptor.
