1. 读图像，显示图像，保存图像读图像，显示的格式有：彩色(1) cv2.IMREAD_COLOR，灰度(0) cv2.IMREAD_GRAYSCALEimport cv2img = cv2.imread('01.png', cv2.IMREAD_COLOR)cv2.imshow('image', img)k = cv2.waitKey(0)cv2.imwrite('02.png', img

1.用ffmpeg将视频转换为yuv格式ffmpeg.exe -i src.avi -c:v rawvideo -pix_fmt yuv420p 1280x720.yuv输出视频可以用yuvPlayer打开2.用ffmpeg将jpg,png图像转换为yuv格式建议图像命名为宽乘高 width*height，乘号用字母”x”。 使用ffmpeg的命令为：ffmpeg.exe -i 1024x680.

开始用Visual studio安装使用opencv。 建议创建头文件，声明所有函数和include，并命名/*版权声明：....版本号：作者:时间：*/#ifndef FIRST_H // if not defined#define FIRST_H#include <iostream>using namespace std;void neo(); // declaration f

1. OpenCV3opencv3 与cuda8不兼容，不启动支持cuda 真的是历经千辛啊安装依赖库sudo apt-get install cmake git pkg-config libgtk2.0-dev libavcodec-dev libavformat-dev libswscale-dev sudo apt-get install python-dev python-openC
