# 基于Paddle+Flask的眼部医疗辅助系统（前后端分离）
视频链接：https://www.bilibili.com/video/BV1k54y1s7j9
# 1. 项目简介：
本项目基于PaddleX提供的FastSCNN语义分割模型，在眼部图像视盘分割数据集上进行训练，并开发了前后端分离项目。
后端代码基于Flask开发，前端WEB界面基于VUE开发。
# 2. 训练语义分割模型：
```python
! pip install paddlex -i https://mirror.baidu.com/pypi/simple
```

# 3. 模型预测
使用模型进行预测，同时使用`pdx.seg.visualize`将结果可视化，可视化结果将保存到`./output/deeplab`下，其中`weight`代表原图的权重，即mask可视化结果与原图权重因子。
```python
import paddlex as pdx
model = pdx.deploy.Predictor('inference_model')
image_name = 'optic_disc_seg/JPEGImages/H0005.jpg'
result = model.predict(image_name)
pdx.seg.visualize(image_name, result, weight=0.4, save_dir='./output/deeplab')
```
2021-01-23 08:16:45 [INFO] The visualized result is saved as ./output/deeplab/visualize_H0005.jpg
```python
!zip -r inference_model/ weights.zip
```

zip error: Nothing to do! (try: zip -r inference_model/ . -i weights.zip)
# 4. 启动WEB应用：
在 Flask 项目下运行以下代码启动后端：
```
python app.py
```
在 VUE 项目下运行以下代码安装依赖：
```
npm install
```
运行以下代码启动前端：
```
npm run serve
```
然后在浏览器打开Localhost即可：
