Did you play around with Inpaint and texture synthesis at all? I feel like the natural next step for this is to remove the old fish, fill in the background with texture synthesis and then put the new fish into the picture.

Either way, I'm really excited to work thru and understand your RadialBasisInterpolation function. I've needed this for my own projects and the interpolating function I've made haven't been satisfactory.

Hi Sean,

Thank you so much for your excellent suggestion! I have never used Inpaint before but judging by the documentation, it seems to be the perfect place to start. Regardless, this is a great idea and I'm really excited to play with it.

I'm really happy to hear about your future plans. I've tried to include a brief description of my RadialBasisInterpolation function with this post but if you're interested in learning more about it I would encourage you to check out the following resources: -

1. A Practical Guide to Radial Basis Function: provides a good in-depth review of RBFs
2. Approximate Thin Plate Spline Mappings: explains different approximation methods for TPS Mappings and Principal Warps

Best,

Manan
