1. 人脸检测的高正确率，误检，漏检很少，支持多脸（max=32）。 平面旋转高达 60 度，并带鼻，嘴定位，及眼镜判断等功能。 2. 支持双目(双摄像头)/多目的 3D 维度识别,增加了人脸的特征集,再次提高识别精度,并有效防止照片通过。 3. 人脸识别的高精度，向用户推荐的识别阀值不仅能适应光线环境的变化，具备满足实际应用的识别正确率。带 眼镜或头发挡住眉毛都行。（但黑粗边眼镜的识别率相对低些，即在较好的识别环境下，黑粗边眼镜仍是 OK 的，只要看得清眼球，就对识别率没有任何影响） 4. 在背光模式下（看上去黑黑的一大片），开启背光识别的开关后，识别速度会减低，把识别阀值调低一些，就 仍然能进行准确的识别。 5. 支持双目，对高清大图，开启二次精定位开关后，能准确地定位人眼中的瞳孔。准确的人眼定位，使 用户能在此基础上开发出多款有创意的延伸产品。(1. Face detection has high accuracy, false detection and few missed detection. It supports multiple faces (max = 32). Plane rotation up to 60 degrees, and with nose, mouth positioning, and glasses judgment and other functions. 2. Support binocular (dual camera) / multi-purpose 3D dimension recognition, increase the feature set of face, improve the recognition accuracy again, and effectively prevent photos from passing. 3. High accuracy of face recognition. The recognition threshold recommended to users can not only adapt to the changes of light environment, but also meet the recognition accuracy of practical application. Wear glasses or hair over your eyebrows. (but the recognition rate of black spectacles is relatively low, that is to say, in a better recognition environment, black spectacles are still OK, as long as you can see the eyeball clearly, there is no impact on the recognition rate.))
