Rapid Object Detection Using a Boosted Cascade of Simple Features (Viola–Jones Face Detection)
Paul Viola and Michael Jones, then at Compaq CRL and Mitsubishi Electric Research Laboratories respectively, published a cascaded boosting framework for real-time face detection, first presented at CVPR in December 2001 and consolidated in the International Journal of Computer Vision in 2004. The method ran at frame rates suitable for live video on consumer hardware.
