摘要
利用小波分析理论和GVF(梯度矢量流)Snake动态轮廓模型方法,提出了一种图像边缘检测的新方法-WVF(小波变换矢量流)Snake模型。计算机模拟表明,该方法克服了小波分析方法得到的边缘不连续的缺点,同时比GVFSnake模型具有更好的抗噪性。从而提高了动态轮廓模型方法检测复杂图像边缘线的能力。
A new images edge-detection method-Wavelets Vector Flow Snake model method is put forward on the basis of the wavelets theory and GVF snake model. Computer simulation results show that the method solves the uncontinuity of the edge produced by the warelets mothod and improves the anti-noise a-bility of the GVF Snake model, enhances the ability of the Snake model to detect the complicated images.
