Hi all, I talked with Kshitij about this idea at length. I am sure that he can do a good job. He has the programming skills and has academic background in image processing and computer vision.
I am willing to co-mentor him. Kshitij, You did not include the extensions we discussed. Estimating the shift between two georeferenced images, matching rasters with vector datasets.
