Fast Multi-Face Detection Algorithm Based on Hausdorff Distance

This paper provides a fast and accurate algorithm of multi-face detection that is robust to the change of background and light. Because the multi-template matching algorithm based on Hausdorff Distance is very complex, many resolution techniques, such as decrease the dimension of model, find the area of interest, and get the fittest model based on the distance between transformation, have been used to advance the computation efficiency. The algorithm's performance was proved by experiment results.
