import cv2 as cvimg = cv.imread("test.jpg")cv.imshow("test",img)cv.waitKey(10000)报错1：module cv2 has no ‘imread’ member原因：VSCode插件检测不到模块, 因为cv2模块下还有cv2模块。解决办法：此段代码运行是没有问题的，但是VSCode会有红色波浪线提示，...

深度学习中，通常需要对数据进行增强处理 Data Augmentaion，再训练数据。常用的数据增强方法有1、翻转变换 flip（左右/上下）2、随机修剪 random crop3、色彩抖动 color jittering4、平移变换 shift5、尺度变换 scale6、对比度变换 contrast7、噪声扰动 noise8、旋转变换/反射变换 Rotation/...

OpenCV中用imread来实现图像文件读取的，用法：#include &lt;opencv2/highgui,hpp&gt;cv::Mat  image;1、双右斜线法：image = cv::imread(” C:\\desktop\\1.bmp “);2、双左斜线法image = cv::imread(” C:\\desktop\\1.bmp “);3、单左斜线...

图像拷贝有两种概念：cv::Mat image;1：浅拷贝当图像之间进行赋值时，图像数据并未发生复制，两个对象指向同一块内存,改变图像2会影响图像1cv::Mat img;img = image;2：深拷贝当图像之间进行赋值时，图像数据发生复制，两个对象指向不同的内存,改变图像2不会影响图像1cv::Mat img;img.copyTo(image);img...

错误提示如图：原因：没有安装libgtk2.0-dev和pkg-config  ，这两依赖项要先于opencv安装安装方式：sudo apt-get install libgtk2.0-dev                      sudo  apt-get install pkg-config安装完成后，再安装opencv即可...
