摘要

Blending or averaging of two-dimensional shapes usually operates on sets of discrete points orpolygons approximating the objects. This relies on a series of evenly distributed or properly positionedpoints on the boundary of the objects. Features or characteristics of the objects are not wellconsidered. This paper presents a simple but effective technique for blending 2D shapes composed ofcurve segments. Features that are essential for shape blending are extracted. Correspondencebetween features of the objects are then established. The correspondence between points on a pair ofcorresponding features are finally established for the interpolation process. This allows characteristicfeatures of the objects to be retained in the blending operation which is essential in industrial design.An experimental system was developed for blending 2D contours with curved boundary. Test resultsshowed that the proposed approach produces results suitable for industrial design.
