Dear Geoscientists,

I am happy to announce ImageQuilting.jl, a geostatistics/computer vision package I’ve been working on since Julia v0.3. I’ve tested it extensively, but I would like to get your feedback if possible.

This package implements an extension to the famous Efros-Freeman algorithm for texture synthesis and transfer in computer vision. Unlike the original algorithm developed for 2D images, our method can also handle 3D grids and pre-existing point-data very efficiently (the fastest in the literature). This is useful for generating alternative models of the subsurface of the Earth when data is available at a few locations (e.g. wells) or at low resolution (e.g. seismic). You can find out more in the Examples section of the documentation.

The corresponding paper is coming out in a few days, I appreciate if you can report issues or give suggestions of improvement before it is out.

I would like to thank the community for the constant help in forums and on GitHub, it is being a pleasure to learn from you. Special thanks to @tim.holy, @yuyichao, @vchuravy, and @tkelman.

Thank you,
