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.

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( "Result window", CV_WINDOW_AUTOSIZE );
imshow( "Result window", dst );
//imwrite("C:\\Users\\arjun\\Desktop\\opencv-dst.jpg",dst);

return 0;
