I have two pictures of the same scene in different light profiles that I would like to superimpose so I know the coordinates to transfer markers between the images. They are of different dimensions, colour and resolution so I have used an edge detector to obtain two similar edge maps of the images.

I would like to know a robust method for matching these edges on each other, or another way of superimposing the original images accurately.

I have a lot of pairs like this and the location of the zoomed image within the other is not the same each time.

You may find some of the following resources useful. MATLAB is capable of matching features and can also be used for edge detection. There might be a way to use this information to allow MATLAB to perform the matching that you require.
