Detailed Description
SoAutoCorrelationProcessing2d engine computes the cross correlation of an image by itself.
The SoAutoCorrelationProcessing2d engine computes the cross correlation of an image by itself in a given window size.
![\[O(n,m)=\frac{1}{2K}\sum_{i=-q}^{q}\sum_{j=-r}^{r}g(n-i,m-j)\]](form_448.png)
![\[\mbox{where}~ g(l,k)=I(l,k)\times I(l+S,k)+I(l,k)\times I(l,k+S)\]](form_449.png)
For a window of size 
in X and 
in Y.
The 
coefficient is the Normalization coefficient : 
.
The 
coefficient is the size of the window.
