A fast overlap control in image morphing using mass-spring system

A fast and stable deformation model is essential for realistic simulation of image morphing. In order to stabilize deformation, we used two internal thin plate mass-spring systems. The deformation results are globally smoother and more stable. One-to-one deformation is one of the important issues in image morphing. We focus on fast removing overlaps in the process of deformation. To rapidly remove overlaps, the external forces are set automatically on its eight neighboring nodes. The speed of removing overlaps is faster when external forces are set on eight neighbouring nodes than when on two neighbouring nodes.
