I have two images, an Original (I) and an image that is a subregion of the original image, called Icrop.
I want to find the coordinates that this subregion was taken from.
I have used the following example from the help page
tformEstimate=imregcorr(I,Icrop)
Rfixed=imref2d(size(Icrop))
moving_region=imwarp(I,tformEstimate,'OutputView',Rfixed)
The moving_region gives me the region from I that is the same as the Icrop but I would like to know the coordinates used from the actual original Image I.

https://www.mathworks.com/help/signal/ref/xcorr2.html#buwe7f3 has a specific example about finding a small image within a larger image.
