Motion and Deformation Analysis in Image Sequences Inspired by Virtual Electromagnetic Interaction between Images

摘要

In order to analyze the moving and deforming of the objects in an image sequence, a novel way is presented inspired by the physical electromagnetic interaction. Edges represent the possible borders of objects, and the changes of edges can reflect the change of the object's position or shape. The virtual current along the main edge lines is proposed based on the significant edge extraction in the image. Then the virtual interaction between the current elements in the two related images is studied by imitating the physical electromagnetic interaction between current-carrying wires. The experimental results prove that the magnetic forces on the current elements in one image applied by the other can reflect the local change of edge lines from one image to the other, which is important and much useful in further analysis.
