使用mtcnn进行人脸检测，

使用的模型
public FaceDetModel getFaceDetModel(){
        FaceDetConfig config = new FaceDetConfig();
        //人脸检测模型，SmartJavaAI提供了多种模型选择(更多模型，请查看文档)，切换模型需要同时修改modelEnum及modelPath
        config.setModelEnum(FaceDetModelEnum.MTCNN);
        //下载模型并替换本地路径，下载地址：https://pan.baidu.com/s/10l22x5fRz_gwLr8EAHa1Jg?pwd=1234 提取码: 1234
        config.setModelPath("D:/BaiduNetdiskDownload/SmartJavaAI/人脸模型/人脸检测模型/mtcnn/");
        //只返回相似度大于该值的人脸,需要根据实际情况调整，分值越大越严格容易漏检，分值越小越宽松容易误识别
        config.setConfidenceThreshold(0.5f);
        //用于去除重复的人脸框，当两个框的重叠度超过该值时，只保留一个
        config.setNmsThresh(FaceDetectConstant.NMS_THRESHOLD);
        return FaceDetModelFactory.getInstance().getModel(config);
    }
