一种轮廓线参数的精确提取方法
A Method for Accurately Extracting the Contour Parameters
摘要
Abstract
Aim To present a method used in extracting contour p arameters accurately under the object shape known. Methods Median filter and expectation of first-order derivative algorithms are used. Results The parameters of contour are extracted accurately. C onclusion The result shows that this method can remove the noise and the big flecks effectively in the gray-image and provide subpixel precision. It ca n be easily used for real time detection.关键词
