**The trained PUNet is mainly applied to unwrap very localized, rapidly deforming areas, particularly the mining subsidence as we stated in the manuscript. The proposed dataset generation strategy allows for richer samples, which can enable the retrained PUNet to cope with more complex situations. **

Introduction

This is a TensorFlow (1.13.1) implementation of PUNet. It can be used to unwrap interferograms with dense fringes and severe noise. The resolution of the input interferogram should be about 20m×20m. Any size of the interferogram can be input, but 180×180 pixels is recommended. The input data should be binary files (*.wzp, float32) or Tiff files (*.tif, float32).

Installation

The code was tested with Python 3.6.

1. Clone the repo:

   git clone https://github.com/Wu-Patrick/Deformation-Monitoring.git
   cd Deformation-Monitorin

2. Install dependencies:

   pip install -r requirements.txt

Unwrapping

1. Input arguments: (see full input arguments via python runPUNet.py --help):

usage: runPUNet.py [-h] [--input INPUT] [--output OUTPUT]
                   [--outputPng OUTPUTPNG] [--rows ROWS] [--cols COLS]
                   [--ckpt_dir CKPT_DIR]

2. Run the example：

python runPUNet.py
# or
python runPUNet.py --input data/dataset1/interf --output data/dataset1/unwrapped --outputPng 1 --rows 180 --cols 180
# or
python runPUNet.py --input data/dataset2/interf/300_20190120-20190201.wzp --output data/dataset2/unwrapped --outputPng 1 --rows 300 --cols 300
