| Abstract: | In the construction of the animation drawing of people and animals using a computer, a drastic reduction of human effort will be realized by automating the painting process. This paper describes an automatic painting method in which the closed region in two consecutive line drawings containing more than one closed region can be identified by motion analysis. For each point on the contour of the closed region in the line drawing, the deformation vector representing the deformation of the closed region and the motion vector representing the motion of the closed region, are defined. The sum of the products of the lengths of the formation vector and the motion vector over the whole closed region, is regarded as the magnitude of the motion of that closed region. A large number of different motions can be conceived of for the closed region from frame to frame, and the principle is set that the most probable motion among the possible motions is the one which minimizes the sum of the motions of the closed regions. Based on this principle, the closed region is identified by determining the motion of the closed region between the two line drawings. This paper describes the algorithm of the proposed method and the result of application to the actual animation. [ABSTRACT FROM AUTHOR] |
