[scikit-image] Non-rigid shape matching

[Surya Kasturi]

Is this correct interpretation? 	
	— Do morphological operations and Hough Ellipse transform for ellipse detection? 

I’m thinking of leveraging active contours. Is it possible to place shape constraints on Energy equation in some way? For instance, perform non-rigid shape matching?

Thanks,
Surya
