基于小波变换模极大的多尺度图像边缘检测matlab源代码,该算法采用的是样条小波,为了更好的检测边缘,用多孔算法代替了mallat算法。该算法和mallat快速算法主要区别:
1 多孔算法不需要抽取偶数样本,所以奇异检测定位更准确,相应的重构是不需要插零。2 多孔算法需要对滤波器进行伸缩。-based on wavelet transform modulus maxima of multiscale edge detection Matlab source code, The algori

边缘检测1.制作一张包括色块、线条的单色背景图片,先对其作低通滤波产生一幅色块和线条边缘模糊的降质图片待处理,采用任意二种边缘检测算法检测待处理图片中的色块和线条的边缘,得到二值化的处理结果图。从结果图中提取色块和线条的边界坐标值,与实际生成原始图像时采用的真实坐标数据作比较,对产生的检测误差作分析。2.拍摄一张包含待检测物体的黑白或者彩色照片,试采用一种边缘检测的算法做待检测物体的自动提取,对生成的结果作分析。-Edge Detection 1. To produce a including
