harris角点检测 python 非极大值抑制 harris角点检测代码,OpenCV中常用的角点检测为Harris角点和ShiTomasi角点。以OpenCV源代码文件.\opencv\sources\samples\cpp\tutorial_code\TrackingMotion\cornerDetector_Demo.cpp为例,主要分析其中的这两种角点检测源代码。角点检
【python代码如下】 import cv2 import numpy as np #读入图像并转化为float类型,用于传递给harris函数 filename = 'Dick.jpg' img = cv2.imread(filename) gray_img = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY) gray_img = np.float32(gray_img) #对图像执行harris Harris_detector = cv2.cornerHarris(gray...

我们知道角点是图像里在各个方向变化最大的区域。早起尝试找到这些角的是Chris Harris和Mike Stephens,在他们的论文A Combined Corner and Edge Detector里,所以现在叫Harris角点检测。他把这个简单想法用数学形式表达,基本上就是对(u,v)在各个方向移动找强度的变化。表达式如下: ...
