| 摘 要： | 文中提出了一种改进型Canny边缘检测算法.采用二维高斯函数的一阶偏导数构造滤波器计算梯度幅值,定义多个不同尺度的高斯滤波器根据各个尺度的滤波器对噪声的抑制能力及边缘定位能力的不同,自适应地确定相应的权值大小,然后再将这些不同尺度下检测到的梯度图像用自适应确定的权值进行加权合成最终的梯度图像.最后引入数学形态学方法对边...

| Abstract: | In this thesis,an improved Canny edge detection algorithm is represented。The filter operator constructed with the first order partial derivative of two-dimensional Gaussian function is employed to compute gradient.Then the multiple Gaussian filters of different scale are defined,Based on the different noise restrain and edge detection ability of the filters of different scale,adaptive weights are calculated and used to form a synthesized gradient image.And finally,edge thin operation was conducted based on morphological operator to obtain single pixel level edge.Experimental results show that it is obvious to suppress the noise and indicate the feasibility and validity of the improved algorithm. |
