Automatic Image Colorization

PRs Welcome License: GPL v3 Template from jarvis

Overview

This is a TensorFlow implementation of the Residual Encoder Network based on Automatic Colorization and the pre-trained VGG16 model from https://github.com/machrisaa/tensorflow-vgg

For latest TensorFlow with estimator support, check tf-1.12 branch. (still under development, the training code is working now)

Structure

  • config.py: config variables like batch size, training_iters and so on
  • image_helper.py: all functions related to image manipulation
  • read_input.py: all functions related to input
  • residual_encoder.py: the residual encoder model
  • common.py: the common part for training and testing, which is mainly the workflow for this model
  • train.py: train the residual encoder model using TensorFlow built-in AdamOptimizer
  • test.py: test your own images and save the output images

How to use

  • Download pre-trained VGG16 model vgg16.npy to vgg folder

  • Option 1: Use pre-trained residual encoder model

    • Download model here
    • Unzip all files to summary_path (you can change this path in config.py)
  • Option 2: Train your own model!

    1. Change the batch_size and training_iters if you want.
    2. Change training_dir to your directory that has all your training jpg images
    3. Run python train.py
  • Test

    1. Change testing_dir to your directory that has all your testing jpg images
    2. Run python test.py
