PyCV - A Computer Vision Package for Python Incorporating Fast Training of Face Detection

PyCV is a package of C++ and Python modules implementing various algorithms that are useful in computer vision, and augments the capabilities of OpenCV. In particular, PyCV provides implementations for:

  • Fast training and selection of Haar-like features for a weak classifier [Pham2007b]. This is currently the world's fastest method for training a face detector. It runs in just a few hours, while most existing methods run in days or weeks.
  • Asymmetric Online Boosting [Pham2007a]: a variant of AdaBoost that learns incrementally using an asymmetric goal as the learning criterion.

Additionally, PyCV contains many useful modules for computer vision and machine learning, specially boosting techniques, Haar-like features, and face detection.

The package is primarily developed by Minh-Tri Pham, as part of his PhD research on face detection. This research is being carried out in the Centre for Multimedia & Network Technology (CeMNet), School of Computer Engineering, Nanyang Technological University, Singapore.
