前言:距离变换 距离变换的主要目的是通过识别目标点和背景点,将二值图像转换为灰度图像。 距离变换主要分为欧氏距离变换和非欧氏距离变换。 非欧距离变换包括棋盘距离变换、城市街区距离变换和倒角距离变换。 棋盘距离:| x1 - x2 | + | y1 - y2 | 城市街区距离:max( | x1 - x2 |, | y1 - y2 | ) ...
the basic form of chamfer distance is calculated as Boosting Chamfer Matching by Learning Chamfer Distance Normalization 453 d(cTha,Em) (x) = 1 |T | xt∈T min ||(xt xe∈E + x) − xe||2 , (1) where ||.||2 is l2 norm and |T | denotes number of points in template T . ...
The step difference of the chamfer after grinding is then detected by the detector 57, after grinding either one edge by a grindstone 54, the moving distance of the grindstone 54 affording the predetermined step difference is stored and all the other edges R2-R6, L2-L6 are subjected to ...
