PredRNN++

This is a TensorFlow implementation of PredRNN++, a recurrent model for video prediction as described in the following paper:

PredRNN++: Towards A Resolution of the Deep-in-Time Dilemma in Spatiotemporal Predictive Learning, by Yunbo Wang, Zhifeng Gao, Mingsheng Long, Jianmin Wang and Philip S. Yu.

Setup

Required python libraries: tensorflow (>=1.0) + opencv + numpy.
Tested in ubuntu/centOS + nvidia titan X (Pascal) with cuda (>=8.0) and cudnn (>=5.0).

Datasets

We conduct experiments on three video datasets: Moving Mnist, Human3.6M, KTH Actions.
For video format datasets, please extract frames from original video clips and move them to the data/ folder.

Training

Use the train.py script to train the model. To train the default model on Moving MNIST simply use:

python train.py

You might want to change the --train_data_paths, --valid_data_paths and --save_dir which point to paths on your system to download the data to, and where to save the checkpoints.

To train on your own dataset, have a look at the InputHandle classes in the data_provider/ folder. You have to write an analogous iterator object for your own dataset.

At inference, the generated future frames will be saved in the --results folder.

Prediction samples

The ground truth | PredRNN++ | A baseline model.
10 frames are predicted given the last 10 frames.
