 #### 简单的例子
 * 为视频添加马赛克,例子中认为脸是需要打码的区域 ,可以通过切换预训练模型切换自动打码区域(输出结果将储存到 './result')<br>
 ```bash
-python3 deepmosaic.py --media_path ./imgs/ruoruo.jpg --model_path ./pretrained_models/mosaic/add_face.pth --use_gpu 0
+python deepmosaic.py --media_path ./imgs/ruoruo.jpg --model_path ./pretrained_models/mosaic/add_face.pth --use_gpu 0
 ```
 * 将视频中的马赛克移除,对于不同的打码物体需要使用对应的预训练模型进行马赛克消除(输出结果将储存到  './result')<br>
 ```bash
-python3 deepmosaic.py --media_path ./result/ruoruo_add.jpg --model_path ./pretrained_models/mosaic/clean_face_HD.pth --use_gpu 0
