# Testing
1、Download model parameter and source codes 

2、Resize the input image into 992x992

3、Running 

- In GPU 0:
`python test.py --data_path_test=./your/test/data/path/ --parallel 0 --schema test --batch_size 1`

- In CPU:
`python test.py --data_path_test=./your/test/data/path/ --parallel None --schema test --batch_size 1`

# Training
a) Download training data in [here](https://github.com/gwxie/Document-Dewarping-with-Control-Points/tree/main/Source/dataset/fiducial1024).

b) Run `python train.py --data_path_train=./your/train/data/path/ --data_path_validate=./your/validate/data/path/ --data_path_test=./your/test/data/path/ --batch_size 32 --schema train --parallel 01`

# Use your Dataset
The training dataset can be synthesised using the [scripts](https://github.com/gwxie/Synthesize-Distorted-Image-and-Its-Control-Points).

# Q&A
1. Q:How to adjust the output image resolution？
A: Adjusting the ‘flat_shap’ or 'output_shape' in utilsV4.py.

2. Q:How to open '*.gw' files?

'im' is input images; 'lbl' is control points; 'segment' is the intervals of points between the horizontal and vertical directions;

3. Q:How to train the model again with 61 points?
