What is this?

This repo complements our repo with the training pipeline used for our ECCV-2016 work.

I want to use it, Where can I start?

You can find a complete example of our project here. It covers data pre-processing, training and inference.

After training, you can plug-in a model trained here in our clean and simplified inference project.

Installation and Usage

Install

We use conda for deployment. You can create an evironment for this project with the environment-proto-linux-x64.yml.

Dependencies: gcc, CUDA, conda.

Are you a bash user? Take a look at our install.sh script.

Usage

Once all the dependencies are installed, you are ready to go.

• Most of the scripts and tools should be executed from the project folder.

• You can add the project dir to your PYTHONPATH and use our modules as standard python package.

Are you bash & modules-env user? Take a look at our activate.sh script.

What is not here?

This repo does not extract the C3D feature vector representation of your videos. However, we try to alleviate your pain installing and assembling all the cumulus of data such that you do not start from scratch.

• Take a look of this branch for help to install C3D.

• Do you want to extract C3D from frames? Take a look at this tool to simplify your life extracting frames from videos.

• Extract C3D for frames without modifying prototxt manually. Take a look at this
