Complete backend for the Riichi Mahjong Calculator tile recognition system. The "Mahjong OCR" works by first splitting the base image into tiles using Darkflow's object detector (tiny-flow-voc3) and then classifies these images using google's mobilenet v1 model.

To setup and run this server, the file structure should be similar with a darkflow folder installed at the root directory as well.

darkflow and all of it's dependencies: Darkflow -> Python3, tensorflow 1.0, numpy, opencv 3

express, fs-extra, mkdrip, socket.io

To run the server locally node server/indexOld. The server listens for socket.io events for "Img" which will process the image as data input.
