- Deep Learning for Disaster Recoveryhttps://github.com/jackkwok/neural-road-inspector
I attempted to automatically annotate flooded, washed out, or otherwise severely damaged roads using state-of-the-art deep learning methods. My goal was to create a tool to help detect and visualize anomalous roads in a simple user interface.
