Abstract: Computer vision has almost solved the issue of in the wild face detection, using complex techniques like convolutional neural networks. On the contrary many open source computer vision frameworks like OpenCV have not yet made the switch to these complex techniques and tend to depend on well established algorithms for face detection, like the cascade classification pipeline suggested by Viola and Jones. The accuracy of these basic face detectors on public datasets like FDDB stays rather low, mainly due to the high number of false positive detections. We propose several adaptations to the current existing face detection model training pipeline of OpenCV. We improve the training sample generation and annotation procedure, and apply an active learning strategy. These boost the accuracy of in the wild face detection on the FDDB dataset drastically, closing the gap towards the accuracy gained by CNN-based face detectors. The proposed changes allow us to provide an improved face de tection model to OpenCV, achieving a remarkably high precision at an acceptable recall, two critical requirements for further processing pipelines like person identification, etc. (More)
