Abstract :
Level set method is being applied actively in image field due to its mathematical perfection and maturity. In this paper, based on Mumford-Shah model with Level Set method, the finite difference and third order TVD (total variation diminishing) Runge-Kutta schemes are employed for space and time discretization respectively to solve the model equation. The computation of license plate localization shows that better edge detection results from level set method are obtained compared to those from other edge detection methods such as Roberts, Sobel and Canny. This study result is very valuable to edge detection, object localization and tracing. Keywords: level set method; license plate recognition; object localization
