CascadeSVMs

Introduction

CascadeSVMs is an open source C++ implementation of the CascadeSVMs algorithm (bounded with LIBLINEAR) for highly imbalanced large-scale data (i.e., negative samples >> positive samples) learning.

Compiling

To compile the code, you need to have the OpenCV library (tested with OpenCV-2.4.6).

Training and Testing

The interface is designed for TRECVID Surveillance Event Detection. It can be modified according to your tasks.

./CascadeSVMs -c train.control -p train

./CascadeSVMs -c test.control -p test

The configuration and parameter settings are embeded in the training and testing control files.

Bugs and Extensions

If you find any bug or develop some extensions, please feel free to drop me a line.
