             abstract = "Face detection is already incorporated in many biometrics and 
                         surveillance applications. Therefore, the reduction of false 
                         detections is a priority in those systems. However, face detection 
                         is still challenging. Many factors, such as pose variation and 
                         complex backgrounds, contribute to false detections. Besides, the 
                         fidelity of a true detection, measured by precision rate, is a 
                         concern in content-based information retrieval. Following those 
                         issues, combinations of methods are developed focusing on 
                         balancing the trade-off between hit-rate and miss-rate. In this 
                         paper, we present an approach that improves face detection based 
                         on a post-processing of skin features. Our method enhanced the 
                         performance of weak detectors using a straightforward and low 
                         complex skin percentage threshold constraint. Furthermore, we also 
                         present a statistical analysis comparing our approach and two face 
                         detectors, under two different conditions for skin detection 
                         training, using a robust dataset for testing. The experimental 
                         results showed a significant drop in the number of false 
                         positives, reducing in 53%, while the precision rate was elevated 
                         in almost 5% when the Viola-Jones approach was used as face 
                         detector.",
