Abstract
In this article, we decipher the Viola-Jones algorithm, the first ever
real-time face detection system. There are three ingredients working in
concert to enable a fast and accurate detection: the integral image for
feature computation, Adaboost for feature selection and an attentional
cascade for efficient computational resource allocation. Here we propose
a complete algorithmic description, a learning code and a learned face
detector that can be applied to any color image. Since the Viola-Jones
algorithm typically gives multiple detections, a post-processing step is
also proposed to reduce detection redundancy using a robustness argument.
