filter2D Convolves an image with the kernel. C++: void filter2D(InputArray src, OutputArray dst, int ddepth, InputArraykernel, Point anchor=Point(-1,-1), double delta=0, int borderType=BORDER_DEFAULT ) Python: cv2.filter2D(src, ddepth, kernel[, dst[,
1.常用命令 调用cmd窗口 Win+R cmd命令窗口清屏 cls cmd命令窗口在运行python时清屏 import os i=os.system('cls') cmd命令窗口在运行python时清除某个变量,但此时赋值仍储存在内存中,会有python的内存管理机制定时清除赋值 del variation cmd命令窗口退出python ctrl+Z,然后enter回车 或exit() cmd命令窗口查看所在目录所有文件 dir cmd命令窗口中切换路径 cd Desktop\paper
拉普拉斯线性滤波,.边缘检測 . When ksize == 1 , the Laplacian is computed by filtering the image with the following aperture: Laplace 计算图像的 Laplacian 变换 void cvLaplace( const CvArr* src, CvArr* dst, int aperture_size=3 ); src 输入图像. dst 输出图像. aperture_size 核大小 (
''' 本次来学习基于opencv进行各种画图操作,以前只习惯用matplotlib,最近开始用opencv,觉得也很好用. cv.line(), cv.circle() , cv.rectangle(), cv.ellipse(), cv.putText() In all the above functions, you will see some common arguments as given below: img : The image where you want to draw t
1.ushort用法? USHORT is a macro which is not part of the official C++ language (it's probably defined or typedef'ed somewhere). unsigned short is an official type defined by the C++ language as an integer that can at least hold numbers between 0 and 65
