Photo-Sketching: Inferring Contour Drawings from Images

This repo contains the training & testing code for our sketch generator. We also provide a [pre-trained model].

For technical details and the dataset, please refer to the [paper] and the [project page].

Setting up

The code is now updated to use PyTorch 0.4 and runs on Windows, Mac and Linux. For the obsolete version with PyTorch 0.3 (Linux only), please check out the branch pytorch-0.3-obsolete.

Windows users should find the corresponding .cmd files instead of .sh files mentioned below.

One-line installation (with Conda environments)

conda env create -f environment.yml

Then activate the environment (sketch) and you are ready to go!

See here for more information about conda environments.

Manual installation

See environment.yml for a list of dependencies.

Using the pre-trained model

• Download the pre-trained model
• Modify the path in scripts/test_pretrained.sh
• From the repo's root directory, run scripts/test_pretrained.sh

It supports a folder of images as input.

Train & test on our contour drawing dataset

• Download the images and the rendered sketch from the project page
• Unzip and organize them into the following structure:

• Modify the path in scripts/train.sh and scripts/test.sh
• From the repo's root directory, run scripts/train.sh to train the model
• From the repo's root directory, run scripts/test.sh to test on the val set or the test set (specified by the phase flag)
