Here is the OpenCv C++ Example on Operation on Arrays by using absdiff()
It calculates the per-element absolute difference between two arrays or between an array and a scalar.
Syntax:
C++: void absdiff(InputArray src1, InputArray src2, OutputArray dst)
Parameters:
src1 – first input array or a scalar.
src2 – second input array or a scalar.
src – single input array.
value – scalar value.
dst – output array that has the same size and type as input arrays.
Here is the Opencv Code for calculating absolute difference of each element of matrix.
//Opencv C++ Example of Operation on Arrays:absdiff #include "opencv2/highgui/highgui.hpp" #include "opencv2/imgproc/imgproc.hpp" #include <iostream> using namespace cv; using namespace std; int main( ) { Mat image1,image2,dst; image1 = imread("C:\\Users\\arjun\\Desktop\\opencv-logo.jpg",CV_LOAD_IMAGE_COLOR); if( !image1.data ) { printf("Error loading image1 \n"); return -1;} image2 = imread("C:\\Users\\arjun\\Desktop\\opencv-test.png",CV_LOAD_IMAGE_COLOR); if( !image2.data ) { printf("Error loading image2 \n"); return -1;} absdiff( image1, image2, dst); namedWindow( "Display window", CV_WINDOW_AUTOSIZE ); imshow( "Display window", image2 ); namedWindow( "Display windo", CV_WINDOW_AUTOSIZE ); imshow( "Display windo", image1 ); namedWindow( "Result window", CV_WINDOW_AUTOSIZE ); imshow( "Result window", dst ); //imwrite("C:\\Users\\arjun\\Desktop\\opencv-dst.jpg",dst); waitKey(0); return 0; }
