Yang WW, Feng JQ, Jin XG, Peng QS. 2-D polygon blending based on feature decomposition. Journal of Software, 2005,16(2):309−315. Abstract: 2-D polygon blending has been widely used in 2-D character animation, pattern matching, and geometric modeling. Previous algorithms tend to use the polygon's geometric elements such as edge length, angle, area, skeleton to associate the regions on the two shapes that look alike. However they ignore the visual features of two polygonal shapes. This paperdoi:10.1360/jos160309 fatcat:p2jc44pbfnecxcqzfbnezywcya
