PredCNN

This is a TensorFlow implementation of PredCNN, an entire convolutional model for video prediction as described in the following paper:

PredCNN: Predictive Learning with Cascade Convolutions, by Ziru Xu, Yunbo Wang, Mingsheng Long and Jianmin Wang.

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 one video dataset, Moving Mnist, and two crowd flow dataset, TaxiBJ and BikeNYC. For other video format datasets, please extract frames from original video clips and move them to the data/ folder.

Training

Use the scripts/train.sh script to train the model. To train the default model on Moving MNIST simply use:

cd scripts;sh train.sh;

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.
