Slicing Convolutional Neural Network for Crowd Video Understanding

This is the source code for "Slicing Convolutional Neural Network for Crowd Video Understanding". It aims at learning generic spatio-temporal features from crowd videos, especially for long-term temporal learning (i.e. 100 frames).

Overview

Three-branch Slicing CNN model (i.e. xy-, xt-, and yt-branch)

Crowd attribute recognition (i.e. 94 crowd-related attributes)

Project Site

Caffe

A fork of the well-known Caffe framework with Multi-GPU training and Dimension Swap layer.

Apart from the official installation prerequisites, we have several other dependencies:

  1. Install openmpi to allow multi-gpu running
  2. Python packages (e.g. numpy, scipy, scikit-image, etc.)
  3. Add export PYTHONPATH="[path_python_layer]:$PYTHONPATH" to ~/.bashrc and restart the terminal. Here [path_python_layer] indicates the absolute path of the python script of py_dim_swap_layer.py.

Get the Caffe code

git clone --recursive https://github.com/amandajshao/Slicing-CNN.git
