# 版面分析
## 1. 简介
版面分析指的是对图片形式的文档进行区域划分，定位其中的关键区域，如文字、标题、表格、图片等。版面分析算法基于[PaddleDetection](https://github.com/PaddlePaddle/PaddleDetection)的轻量模型PP-PicoDet进行开发。

## 4. 开始训练
提供了训练脚本、评估脚本和预测脚本，本节将以PubLayNet预训练模型为例进行讲解。
如果不希望训练，直接体验后面的模型评估、预测、动转静、推理的流程，可以下载提供的预训练模型，并跳过本部分。
```
mkdir pretrained_model
cd pretrained_model
# 下载并解压PubLayNet预训练模型
wget https://paddleocr.bj.bcebos.com/ppstructure/models/layout/picodet_lcnet_x1_0_layout.pdparams
```
### 4.1. 启动训练
开始训练:
* 修改配置文件
如果你希望训练自己的数据集，需要修改配置文件中的数据配置、类别数。
以`configs/picodet/legacy_model/application/layout_detection/picodet_lcnet_x1_0_layout.yml` 为例，修改的内容如下所示。
```yaml
metric: COCO
# 类别数
num_classes: 5
TrainDataset:
!COCODataSet
# 修改为你自己的训练数据目录
image_dir: train
# 修改为你自己的训练数据标签文件
anno_path: train.json
# 修改为你自己的训练数据根目录
dataset_dir: /root/publaynet/
data_fields: ['image', 'gt_bbox', 'gt_class', 'is_crowd']
EvalDataset:
!COCODataSet
# 修改为你自己的验证数据目录
image_dir: val
# 修改为你自己的验证数据标签文件
anno_path: val.json
# 修改为你自己的验证数据根目录
dataset_dir: /root/publaynet/
TestDataset:
!ImageFolder
# 修改为你自己的测试数据标签文件
anno_path: /root/publaynet/val.json
```
* 开始训练，在训练时，会默认下载PP-PicoDet预训练模型，这里无需预先下载。
```bash
# GPU训练 支持单卡，多卡训练
# 训练日志会自动保存到 log 目录中
# 单卡训练
python3 tools/train.py \
-c configs/picodet/legacy_model/application/layout_detection/picodet_lcnet_x1_0_layout.yml \
--eval
# 多卡训练，通过--gpus参数指定卡号
python3 -m paddle.distributed.launch --gpus '0,1,2,3' tools/train.py \
-c configs/picodet/legacy_model/application/layout_detection/picodet_lcnet_x1_0_layout.yml \
--eval
```
正常启动训练后，会看到以下log输出：
```
[08/15 04:02:30] ppdet.utils.checkpoint INFO: Finish loading model weights: /root/.cache/paddle/weights/LCNet_x1_0_pretrained.pdparams

```
- `--eval`表示训练的同时，进行评估， 评估过程中默认将最佳模型，保存为 `output/picodet_lcnet_x1_0_layout/best_accuracy` 。
**注意，预测/评估时的配置文件请务必与训练一致。**
### 4.2. FGD蒸馏训练
PaddleDetection支持了基于FGD([Focal and Global Knowledge Distillation for Detectors](https://arxiv.org/abs/2111.11837v1))蒸馏的目标检测模型训练过程，FGD蒸馏分为两个部分`Focal`和`Global`。`Focal`蒸馏分离图像的前景和背景，让学生模型分别关注教师模型的前景和背景部分特征的关键像素；`Global`蒸馏部分重建不同像素之间的关系并将其从教师转移到学生，以补偿`Focal`蒸馏中丢失的全局信息。
更换数据集，修改【TODO】配置中的数据配置、类别数，具体可以参考4.1。启动训练：
```bash
python3 -m paddle.distributed.launch --gpus '0,1,2,3' tools/train.py \
-c configs/picodet/legacy_model/application/layout_detection/picodet_lcnet_x1_0_layout.yml \
--slim_config configs/picodet/legacy_model/application/layout_detection/picodet_lcnet_x2_5_layout.yml \
--eval
```
- `-c`: 指定模型配置文件。
- `--slim_config`: 指定压缩策略配置文件。
## 5. 模型评估与预测
### 5.1. 指标评估
训练中模型参数默认保存在`output/picodet_lcnet_x1_0_layout`目录下。在评估指标时，需要设置`weights`指向保存的参数文件。评估数据集可以通过 `configs/picodet/legacy_model/application/layout_detection/picodet_lcnet_x1_0_layout.yml` 修改`EvalDataset`中的 `image_dir`、`anno_path`和`dataset_dir` 设置。
```bash
# GPU 评估， weights 为待测权重
python3 tools/eval.py \
-c configs/picodet/legacy_model/application/layout_detection/picodet_lcnet_x1_0_layout.yml \
-o weigths=./output/picodet_lcnet_x1_0_layout/best_model
```
会输出以下信息，打印出mAP、AP0.5等信息。
```py
Average Precision (AP) @[ IoU=0.50:0.95 | area= all | maxDets=100 ] = 0.935
Average Precision (AP) @[ IoU=0.50 | area= all | maxDets=100 ] = 0.979
Average Precision (AP) @[ IoU=0.75 | area= all | maxDets=100 ] = 0.956
Average Precision (AP) @[ IoU=0.50:0.95 | area= small | maxDets=100 ] = 0.404
Average Precision (AP) @[ IoU=0.50:0.95 | area=medium | maxDets=100 ] = 0.782
Average Precision (AP) @[ IoU=0.50:0.95 | area= large | maxDets=100 ] = 0.969
Average Recall (AR) @[ IoU=0.50:0.95 | area= all | maxDets= 1 ] = 0.539
Average Recall (AR) @[ IoU=0.50:0.95 | area= all | maxDets= 10 ] = 0.938
Average Recall (AR) @[ IoU=0.50:0.95 | area= all | maxDets=100 ] = 0.949
Average Recall (AR) @[ IoU=0.50:0.95 | area= small | maxDets=100 ] = 0.495
Average Recall (AR) @[ IoU=0.50:0.95 | area=medium | maxDets=100 ] = 0.818
Average Recall (AR) @[ IoU=0.50:0.95 | area= large | maxDets=100 ] = 0.978
[08/15 07:07:09] ppdet.engine INFO: Total sample number: 11245, averge FPS: 24.405059207157436
[08/15 07:07:09] ppdet.engine INFO: Best test bbox ap is 0.935.
```
使用FGD蒸馏模型进行评估：
```
python3 tools/eval.py \
-c configs/picodet/legacy_model/application/layout_detection/picodet_lcnet_x1_0_layout.yml \
--slim_config configs/picodet/legacy_model/application/layout_detection/picodet_lcnet_x2_5_layout.yml \
-o weights=output/picodet_lcnet_x2_5_layout/best_model
```
- `-c`: 指定模型配置文件。
- `--slim_config`: 指定蒸馏策略配置文件。
- `-o weights`: 指定蒸馏算法训好的模型路径。
### 5.2. 测试版面分析结果
预测使用的配置文件必须与训练一致，如您通过 `python3 tools/train.py -c configs/picodet/legacy_model/application/layout_detection/picodet_lcnet_x1_0_layout.yml` 完成了模型的训练过程。
使用 PaddleDetection 训练好的模型，您可以使用如下命令进行中文模型预测。
```bash
python3 tools/infer.py \
-c configs/picodet/legacy_model/application/layout_detection/picodet_lcnet_x1_0_layout.yml \
-o weights='output/picodet_lcnet_x1_0_layout/best_model.pdparams' \
--infer_img='docs/images/layout.jpg' \
--output_dir=output_dir/ \
--draw_threshold=0.4
```
- `--infer_img`: 推理单张图片，也可以通过`--infer_dir`推理文件中的所有图片。
- `--output_dir`: 指定可视化结果保存路径。
- `--draw_threshold`:指定绘制结果框的NMS阈值。
预测图片如下所示，图片会存储在`output_dir`路径中。
使用FGD蒸馏模型进行测试：
```
python3 tools/infer.py \
-c configs/picodet/legacy_model/application/layout_detection/picodet_lcnet_x1_0_layout.yml \
--slim_config configs/picodet/legacy_model/application/layout_detection/picodet_lcnet_x2_5_layout.yml \
-o weights='output/picodet_lcnet_x2_5_layout/best_model.pdparams' \
--infer_img='docs/images/layout.jpg' \
--output_dir=output_dir/ \
--draw_threshold=0.4
```
## 6. 模型导出与预测
### 6.1 模型导出
inference 模型（`paddle.jit.save`保存的模型） 一般是模型训练，把模型结构和模型参数保存在文件中的固化模型，多用于预测部署场景。 训练过程中保存的模型是checkpoints模型，保存的只有模型的参数，多用于恢复训练等。 与checkpoints模型相比，inference 模型会额外保存模型的结构信息，在预测部署、加速推理上性能优越，灵活方便，适合于实际系统集成。
版面分析模型转inference模型步骤如下：
```bash
python3 tools/export_model.py \
-c configs/picodet/legacy_model/application/layout_detection/picodet_lcnet_x1_0_layout.yml \
-o weights=output/picodet_lcnet_x1_0_layout/best_model \
--output_dir=output_inference/
```
* 如无需导出后处理，请指定：`-o export.benchmark=True`（如果-o已出现过，此处删掉-o）
* 如无需导出NMS，请指定：`-o export.nms=False`
转换成功后，在目录下有三个文件：
```
output_inference/picodet_lcnet_x1_0_layout/
├── model.pdiparams # inference模型的参数文件
├── model.pdiparams.info # inference模型的参数信息，可忽略
└── model.pdmodel # inference模型的模型结构文件
```
FGD蒸馏模型转inference模型步骤如下：
```bash
python3 tools/export_model.py \
-c configs/picodet/legacy_model/application/publayernet_lcnet_x1_5/picodet_student.yml \
--slim_config configs/picodet/legacy_model/application/publayernet_lcnet_x1_5/picodet_teacher.yml \
-o weights=./output/picodet_lcnet_x2_5_layout/best_model \
--output_dir=output_inference/
```
### 6.2 模型推理
版面恢复任务进行推理，可以执行如下命令：
```bash
python3 deploy/python/infer.py \
--model_dir=output_inference/picodet_lcnet_x1_0_layout/ \
--image_file=docs/images/layout.jpg \
--device=CPU
```
- --device：指定GPU、CPU设备
模型推理完成，会看到以下log输出
```
