The code is now outdated and will not work with current keras versions. The following code will not run as-it-is, however, you can look into the code to understand the paper better.

Below you can find Training/Testing Code for our anomaly Detection project which was published in Computer Vision and Pattern Recognition, CVPR 2018.

The implementation is tested using:

Keras version 1.1.0

Theano 1.0.2

Python 3

Ubuntu 16.04

We used C3D-v1.0 (https://github.com/facebook/C3D) with default settings as a feature extractor.

Training_AnomalyDetecor_public.py is to Train Anomaly Detection Model

Testing_Anomaly_Detector_public.py is to test trained Anomaly Detection Model

Save_C3DFeatures_32Segments is to save already computed C3D features for the whole video into 32 segment features.

weights_L1L2.mat: It contains the pre-trained weights for the model ‘model.json’.

Demo_GUI: We have provided a simple GUI which can be used to see results of our approach on sample videos.

SampleVideos: This folder contains C3D features (32 segments) for sample videos. It order to see testing results for the features in this folder, please copy the corrosponding videos in the same folder.

Plot_All_ROC: This code can be use to plot the ROC results reported in the paper. The data to plot ROCs of methods discussed in the paper can be found in folder Paper_Results.

The project page can be found at: https://www.crcv.ucf.edu/projects/real-world/

Temporal_Anomaly_Annotation.txt contains ground truth annotations of the testing dataset.

Anomaly_Train.txt contains the video names for training anomaly detector

FAQs:

Q: Should I use C3D or I3D?

Ans: Several people have emailed me that in their experiments, I3D performs much better than C3D. So I would suggest to first try I3D. Obviously, for this, we need to re-train the model and make small modifications in training and testing codes.
