把CV_8UC1转换到CV32F1实现如下: src.convertTo(dst, CV_32F); === 对图像灰度转换,灰度图反差,RGB图像反差等功能代码实现如下: #include <opencv2/opencv.hpp> #include <iostream> using namespace std; using namespace cv; //只对灰度图像进行反差并在窗口显示 void grayInvert(Mat &gray);//输入单...
示例代码为C++编写,仅供参考。注意,为节省篇幅,函数中省略了参数类型和返回值,实际使用时参考opencv的接口说明即可!因版本不同而出现的接口和参数差异问题,请以具体版本为准,作者使用的opencv版本为最新版。 导航 OpenCV4图像处理算子不完全手册-进阶篇OpenCV4图像处理算子不完全手册-应用篇 正文 一、图像数据读写 1...
