+
+## 一、模型基本信息
+
+- ### 应用效果展示
+ - 样例结果示例：
+
+ 
+
+ 输入内容图形
+
+ 
+
+ 输入风格图形
+
+ 
+
+ 输出图像
+
+
+
+- ### 模型介绍
+
+ - LapStyle--拉普拉斯金字塔风格化网络，是一种能够生成高质量风格化图的快速前馈风格化网络，能渐进地生成复杂的纹理迁移效果，同时能够在512分辨率下达到100fps的速度。可实现多种不同艺术风格的快速迁移，在艺术图像生成、滤镜等领域有广泛的应用。
+
+ - 更多详情参考：[Drafting and Revision: Laplacian Pyramid Network for Fast High-Quality Artistic Style Transfer](https://arxiv.org/pdf/2104.05376.pdf)
+
+
+
+## 二、安装
+
+- ### 1、环境依赖
+ - ppgan
+
+- ### 2、安装
+
+ - ```shell
+ $ hub install lapstyle_circuit
+ ```
+ - 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 lapstyle_circuit --content "/PATH/TO/IMAGE" --style "/PATH/TO/IMAGE1"
+ ```
+ - 通过命令行方式实现风格转换模型的调用，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="lapstyle_circuit")
+ content = cv2.imread("/PATH/TO/IMAGE")
+ style = cv2.imread("/PATH/TO/IMAGE1")
+ results = module.style_transfer(images=[{'content':content, 'style':style}], output_dir='./transfer_result', use_gpu=True)
+ ```
+
+- ### 3、API
+
+ - ```python
+ style_transfer(images=None, paths=None, output_dir='./transfer_result/', use_gpu=False, visualization=True)
+ ```
+ - 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；
+ - style (numpy.ndarray) : 风格图像，shape为 \[H, W, C\]，BGR格式；
+ - 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；
+ - style (str) : 风格图像的路径；
+ - output\_dir (str): 结果保存的路径；
+ - use\_gpu (bool): 是否使用 GPU；
+ - visualization(bool): 是否保存结果到本地文件夹
+
+
+## 四、服务部署
+
+- PaddleHub Serving可以部署一个在线图像风格转换服务。
+
+- ### 第一步：启动PaddleHub Serving
+
+ - 运行启动命令：
+ - ```shell
+ $ hub serving start -m lapstyle_circuit
+ ```
+
+ - 这样就完成了一个图像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/lapstyle_circuit"
+ 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 lapstyle_circuit==1.0.0
+ ```
