This repository contains source codes of the following paper:

Yuki Endo, Yoshihiro Kanamori, Shigeru Kuriyama:
"Animating Landscape: Self-Supervised Learning of Decoupled Motion and Appearance for Single-Image Video Synthesis,"
ACM Transactions on Graphics (Proc. of SIGGRAPH Asia 2019), 38, 6, pp.175:1-175:19, November 2019.

Dependencies

Python (we used version 2.7.12)
PyTorch (we used version 0.4.0)
OpenCV (we used version 2.4.13)
scikit-learn (we used version 0.19.0)

The other dependencies for the above libraries are also needed. It might work with other versions as well.

Animating landscape image

Download the pretrained models(mirror), put them into the models directory, and run test.py by specifying an input image and an output directory, for example,

python test.py --gpu 0 -i ./inputs/1.png -o ./outputs

Three videos (looped motion, flow field, and final result) are generated in the output directory. Output videos might differ according to latent codes randomly sampled every time you run the code.

You can also specify latent codes manually from the pre-trained codebook using simple scalar values for motion (-mz) and appearance (-az) in [0,1], for example,

python test.py --gpu 0 -i ./inputs/1.png -o ./outputs -mz 0.9 -az 0.1

Training new models

Run train.py by specifying a dataset directory and a training mode.

python train.py --gpu 0 --indir ./training_data/motion --mode motion

Trained models are saved in the models directory.

Fore more optional arguments, run each code with --help option.
