Flip and save an image in Opencv - C++

Advertisemen

Add following codes(codes that are highlighted) to the existing codes from our last tutorial.

Like before, we declared variable and named it result.

flip(InputArray src, OutputArray dst, int flipCode)

• src – input array.
• dst – output array of the same size and type as src.
• flipCode – a flag to specify how to flip the array; 0 means flipping around the x-axis and positive value (for example, 1) means flipping around y-axis. Negative value (for example, -1) means flipping around both axes (see the discussion below for the formulas).

imwrite saves image in same folder as original with the name specified.

full codes will look like this :

#include <iostream>
#include <opencv2/core/core.hpp>
#include <opencv2/highgui/highgui.hpp>
int main()
    { 
       cv::Mat image; // 1
       image = cv::imread("binary.jpg"); // 2
       cv::namedWindow("Aarlangdi Original Image"); //3
       cv::imshow("Aarlangdi Original Image", image); // 4
       cv::Mat result;
       cv::flip(image, result, 1);

       cv::namedWindow("windowTwo");
       cv::imshow("windowTwo", result);

       // saving image 
       cv::imwrite("binaryModified.jpg", result);

      cv::waitKey(0); //5
    }
