+# 人脸识别物理对抗攻击
+
+
+
+##描述
+本项目是对人脸识别模型的物理对抗攻击，通过生成对抗口罩，使人脸佩戴后实现有目标攻击和非目标攻击，并应用于MindSpore平台。
+
+
+
+##模型结构
+采用华为MindSpore官方训练的FaceRecognition模型
+https://www.mindspore.cn/resources/hub/details?MindSpore/1.7/facerecognition_ms1mv2
+
+
+
+
+##环境要求
+mindspore=1.7，硬件平台为GPU。
+
+
+
+##脚本说明

+
+
+##模型调用
+方法一:
+
+    #基于mindspore_hub库调用FaceRecognition模型
+
+    import mindspore_hub as mshub
+    from mindspore import context
+    
+    def get_net():
+        context.set_context(mode=context.GRAPH_MODE,
+                            device_target="GPU",
+                            device_id=0)
+        
+        model = "mindspore/1.7/facerecognition_ms1mv2"
+        network = mshub.load(model)
+        network.set_train(False)
+        return network
+
+方法二:
+
+    利用 MindSpore代码仓中的https://gitee.com/mindspore/models/blob/master/research/cv/FaceRecognition/eval.py的get_model函数加载模型
+
+##训练过程
+有目标攻击:
+    
+    $ cd face_adversarial_attack/
+    $ python example_target_attack.py
+
+非目标攻击:
+    
+    $ cd face_adversarial_attack/
+    $ python example_non-target_attack.py
+
+
+
+
+##默认训练参数
+optimizer=adam, learning rate=0.01, weight_decay=0.0001, epoch=2000
+
+
+##评估过程
+评估方法一:
+   
+    adversarial_attack.Attack.test()
+
+
+评估方法二:
+    
+    $ cd face_adversarial_attack/
+    $ python test.py
