Summary

grains is a software package for the tens of tech savy metallurgists and ceramists out there who are tired of counting grains by hand. The goal of this project is to accelerate the process of grain analysis by applying modern computer vision algorithms. This package does not yet have a stable release.

Example

This example showcases the basic functionality of the grains software library. Please note that the scale in this example is ARBITRARY as I have not yet found adequate validation images. Refer to the examples directory for the simple source code used to generate these results.
