+
+- ### 模型介绍
+
+  - PSGAN模型的任务是妆容迁移， 即将任意参照图像上的妆容迁移到不带妆容的源图像上。很多人像美化应用都需要这种技术。
+
+  - 更多详情参考：[PSGAN: Pose and Expression Robust Spatial-Aware GAN for Customizable Makeup Transfer](https://arxiv.org/pdf/1909.06956.pdf)
+
+
+
+## 二、安装
+
+- ### 1、环境依赖  
+  - ppgan
+  - dlib
+
+- ### 2、安装
+
+  - ```shell
+    $ hub install psgan
+    ```
+  - 如您安装时遇到问题，可参考：[零基础windows安装](../../../../docs/docs_ch/get_start/windows_quickstart.md)
+ | [零基础Linux安装](../../../../docs/docs_ch/get_start/linux_quickstart.md) | [零基础MacOS安装](../../../../docs/docs_ch/get_start/mac_quickstart.md)
+
+## 三、模型API预测
+
+- ### 1、命令行预测
+
+  - ```shell
+    # Read from a file
+    $ hub run psgan --content "/PATH/TO/IMAGE" --style "/PATH/TO/IMAGE1"
+    ```
+  - 通过命令行方式实现妆容转换模型的调用，更多请见 [PaddleHub命令行指令](../../../../docs/docs_ch/tutorial/cmd_usage.rst)
+
+- ### 2、预测代码示例
+
+  - ```python
+    import paddlehub as hub
+
+    module = hub.Module(name="psgan")
+    content = cv2.imread("/PATH/TO/IMAGE")
+    style = cv2.imread("/PATH/TO/IMAGE1")
+    results = module.makeup_transfer(images=[{'content':content, 'style':style}], output_dir='./transfer_result', use_gpu=True)
+    ```
+
+- ### 3、API
+
+  - ```python
+    makeup_transfer(images=None, paths=None, output_dir='./transfer_result/', use_gpu=False, visualization=True)
+    ```
+    - 妆容风格转换API。
+
+    - **参数**
+
+      - images (list[dict]): data of images, 每一个元素都为一个 dict，有关键字 content, style, 相应取值为：
+        - content (numpy.ndarray): 待转换的图片，shape 为 \[H, W, C\]，BGR格式；<br/>
+        - style (numpy.ndarray) : 风格图像，shape为 \[H, W, C\]，BGR格式；<br/>
+      - paths (list[str]): paths to images, 每一个元素都为一个dict, 有关键字 content, style, 相应取值为：
+        - content (str): 待转换的图片的路径；<br/>
+        - style (str) : 风格图像的路径；<br/>
+      - output\_dir (str): 结果保存的路径； <br/>
+      - use\_gpu (bool): 是否使用 GPU；<br/>
+      - visualization(bool): 是否保存结果到本地文件夹
+
+
+## 四、服务部署
+
+- PaddleHub Serving可以部署一个在线妆容风格转换服务。
+
+- ### 第一步：启动PaddleHub Serving
+
+  - 运行启动命令：
+  - ```shell
+    $ hub serving start -m psgan
+    ```
+
+  - 这样就完成了一个妆容风格转换的在线服务API的部署，默认端口号为8866。
+
+  - **NOTE:** 如使用GPU预测，则需要在启动服务之前，请设置CUDA\_VISIBLE\_DEVICES环境变量，否则不用设置。
+
+- ### 第二步：发送预测请求
+
+  - 配置好服务端，以下数行代码即可实现发送预测请求，获取预测结果
+
+  - ```python
+    import requests
+    import json
+    import cv2
+    import base64
+
+
+    def cv2_to_base64(image):
+      data = cv2.imencode('.jpg', image)[1]
+      return base64.b64encode(data.tostring()).decode('utf8')
+
+    # 发送HTTP请求
+    data = {'images':[{'content': cv2_to_base64(cv2.imread("/PATH/TO/IMAGE")), 'style': cv2_to_base64(cv2.imread("/PATH/TO/IMAGE1"))}]}
+    headers = {"Content-type": "application/json"}
+    url = "http://127.0.0.1:8866/predict/psgan"
+    r = requests.post(url=url, headers=headers, data=json.dumps(data))
+
+    # 打印预测结果
+    print(r.json()["results"])
+
+## 五、更新历史
+
+* 1.0.0
+
+  初始发布
+
+  - ```shell
+    $ hub install psgan==1.0.0
+    ```
