The Influence of Ear Biometric on Profile Face Detection
摘要
Abstract
In the field of face detection, how to accurately detect and locate faces in the images is a key problem. In order to improve the performance of face detector, the common approach is to add more training datasets or use more robust facial feature representations. Yet, one of the foundational tasks in training face detector is the annotation of the face bounding boxes for the training images. Should the face bounding box include ear information? What is the corresponding influence on the performance of profile face detection? This is an uninvestigated issue. Our experimental results show that, when using profile face datasets and the faces bounding include ear to train the face detector, the accuracy of profile face detector based on DPM (the Deformable Parts Model) decreases by 1. 9％, yet, the recall increases by 6. 3％. In the case of Viola&Jones and Fast R-CNN, the improvements are significant, the corresponding accuracy increases by 6. 8％ and 4. 4％, and recall increases by 14. 9％ and 12. 9％, respectively. This reveals that, when training profile face detection model with the ear information, it can significantly improve the recall of profile face detection.关键词
