摘　　要：在使用人脸检测识别的广告推荐场景中目标用户是正在注视广告屏幕的用户,因此在做广告推荐时需要在检测人脸的同时检测两只眼睛,确保检测抓取的人脸是正对广告设备的人脸。现有的人脸检测加人脸姿态评估算法对硬件资源消耗过大,在低成本硬件上无法保证业务的运行效果,所以该文首先对主流检测器进行全面的比较分析,然后提出了一种基于优化后SSD算法的人脸和双眼协同检测器,可以同时检测人脸和眼睛,并根据人脸和眼睛的位置判断它们是否属于广告推荐对象。该方法增加了人脸和眼睛的位置信息,增加了特征图的大小,并增加了三个卷积层,以获得小目标的低层特征。预测层的数量也被扩展以增加预测的可能性。同时,该方法在实验比较和真实场景试验中均显示出良好的效果。In the scene of advertising recommendation using face detection and recognition,the target user is the user who is staring at the advertising screen.Therefore,when making advertising recommendation,it is necessary to detect both eyes while detecting the face to ensure that the face captured by detection is facing the face of the advertising device.Existing face detection and face pose evaluation algorithms consume too much hardware resources and cannot guarantee the operation effect of services on low-cost hardware.Therefore,we first carry out a comprehensive comparative analysis of the mainstream detector,and then propose a face-eyes co-detector based on optimized SSD algorithm,which can simultaneously detect faces and eyes and judge whether faces and eyes belong to the recommended objects of advertising according to their positions.In this method,the position information of face and eyes is increased,the size of the feature map is increased,and three convolution layers are added to obtain the low-level features of small targets.The number of prediction layers has also been extended to increase the likelihood of prediction.Also the proposed method shows excellent results in both experimental comparison and the trials of the real scenes.
