Abstract:

Aimed at the problem of slow convergence speed and low efficiency for moving target contour extraction,a kind of new algorithm based on difference multiplication and multi-level set with Chan-Vese model are put forward,dealing with the problem of sensitive to the initial position and noise of C-V model. The method uses four adjacent images frames for differential multiply to inhibit and filter most of the background edge,and then extracts moving object contour through multi-level set with C-V model. Experiment results show that this method not only overcomes the difficulty of multi-objects recognition,but also accurately extracts moving target contour more quickly.

Key words: target contour, multi-level set, differential multiply, Chan-Vese
