摘要: 为快速稳定地检测图像序列中角度变化较大、遮挡较为严重的人脸,结合快速精确的目标检测模型MobileNet-SSD (MS)和快速跟踪模型核相关滤波(KCF),提出一种新的自动检测-跟踪-检测(DTD)模式,即MS-KCF人脸检测模型。首先,利用MS模型快速精确地对人脸进行检测,并且更新跟踪模型;其次,将检测到的人脸坐标信息输入到KCF跟踪模型中进行稳定的跟踪,并加快整体的检测速度;最后,为了防止跟踪丢失,跟踪数帧后再次更新检测模型,重新对人脸进行检测。实验显示,在FDDB人脸检测基准中,MS-KCF模型的召回率为93.60%;在WIDER FACE人脸检测基准的Easy、Medium和Hard数据集中,MS-KCF模型的召回率分别为93.11%、92.18%和82.97%,平均速度为193帧/s。实验结果表明,MS-KCF模型具有稳定性和快速性,在图像序列中对严重遮挡和角度变化大的人脸具有很好的检测效果。

Abstract: In order to quickly and stably detect the faces with large change of angle and serious occlusion in image sequence, a new automatic Detection-Tracking-Detection (DTD) model was proposed by combining the fast and accurate target detection model MobileNet-SSD (MS) and the fast tracking model Kernel Correlation Filtering (KCF), namely MS-KCF face detection model. Firstly, the face was detected quickly and accurately by using MS model, and the tracking model was updated. Secondly, the detected face coordinate information was input into the KCF tracking model to track steadily, and the overall detection speed was accelerated. Finally, to prevent tracking loss, the detection model was updated again after tracking several frames, then the face was detected again. The recall of MS-KCF model in the FDDB face detection benchmark was 93.60%; the recall in Easy, Medium and Hard data sets of WIDER FACE benchmark were 93.11%, 92.18% and 82.97%, respectively; the average speed was 193 frames per second. Experimental results show that the MS-KCF model is stable and fast, which has a good detection effect on the faces with serious shadows and large angle changes.
