Myriad ROI Detection Toolkit

Myriad is a fault-tolerant distributed computing framework for creating Region Of Interest (ROI) detection applications. Developed by Emphysic, Myriad provides signal / image processing, machine learning, and concurrency functionality all in a single library.

In 2016 NASA funded the development of a Myriad-based system for automatically detecting indications of structural damage in large Nondestructive Testing (NDT) datasets.

Sample ROI Detection Results

We've put together a demonstration of this system that goes all the way from picking training data to searching for damage:
