Training Yolo on LEGO

This repository contains experiments of transfer learning using YOLO on a new synthetical LEGO data set ROUGH AND UNDOCUMENTED!

Prerequisite

• Tensorflow

Organisation

• dumps_weights_to_pkl.py save tiny yolo weights obtained from darkflow to a pkl
• train.py use those weights to retrain the network defined in tiny_yolo.py
• load.py contains function to save and create Tensorflow graphs including a freeze_graph(folder) that makes a graph as a tensorflow checkpoint reusable
• test.py apply a 'frozen graph' to a test image
