在ubuntu系统上，用KDevelop开发环境写的代码，所以有main.cpp和CMakeLists.txt两个文件。没有KDevelop也可以，直接mkdir build && cd build && cmake … && makemain.cpp#include <iostream>#include <string>#i

img = cv2.resize(img,None,fx=0.5,fy=0.5,interpolation=cv2.INTER_AREA)分别设定长宽倍数，可以大于1，可以小于1

libjpeg.so.9是一个软连接，它指向libjpeg.so.9.2.0这是一个opencv需要的编解码库。这种库的默认搜索路径是/lib/usr/lib/usr/local/lib要在根目录添加这种so库的搜索路径的话，是在/etc/ld.so.conf/etc/ld.so.conf:include 路径需要在个人目录添加这种so库的搜索路径的话，~/.bashrc...

img = cv2.resize(img,None,fx=0.5,fy=0.5,interpolation=cv2.INTER_AREA)分别设定长宽倍数，可以大于1，可以小于1

grep "要查找的字符串" * -r会递归查找所有子目录中文件不止能查找文本文件，还能查找库文件如 .so文件中

官网：https://opencv.org/releases/下载Sources包，我测试下载的是3.4.16安卓opencv依赖库：百度一下”linux编译opencv”Linux编译：mkdir buildcd buildcmake -D WITH_TBB=ON -D WITH_EIGEN=OFF -D OPENCV_GENERATE_PKGCONFIG=ON-D BUILD_DOCS=ON
