In the case of 2 images $m_{1}(x,y)$ and $m_{2}(x,y)$ of size $m×n$ , where $(x,y)$ are the coordinates of the image, the correlation constructs a matrix $A$ where each $A(i,j)$ is the degree of similarity between the image $m_{1}(x,y)$ and $m_{2}(x+i,y+j)$ (note that $m_{2}(x+i,y+i)$ is the image $m_{2}(x,y)$ translated $i$, $j$ pixels). This degree of ...
