A robotic rocks sorter

posted by Jason Kottke   May 23, 2016

Jller is a machine that sorts stones from a specific river according to their geologic age.

The machine works with a computer vision system that processes the images of the stones and maps each of its location on the platform throughout the ordering process. The information extracted from each stone are dominant color, color composition, and histograms of structural features such as lines, layers, patterns, grain, and surface texture. This data is used to assign the stones into predefined categories.
