  • Patent number: 5325475
    Abstract: Computer apparatus and method determines correspondence between two shapes or drawings. Included is a computer matcher which determines point by point matches/correspondence between a source object or drawing and a target object or drawing. As applied to the generation of animation sequences, the computer matcher is given as input a source drawing, a target drawing and at least four working points on the first drawing matched to four working points on the second drawing. The matcher defines a transform vector from the initially given working points of the first drawing and working points of the second drawing and their association. With the transform vector, the matcher performs a vector transformation of each of the remaining points on the first drawing to a respective point on the second drawing. This generates a correspondence and thus match between remaining points on the first drawing with respective remaining points on the second drawing.
