Description

The implemention of NPT, Disentangling Noise Pattern from Seismic Images: Noise Reduction and Style Transfer .

NPT has two key parts, which are named I2I-NT and D2D-NT. I2I-NT provides image to image noise transfer while D2D-NT trains dataset to dataset noise transfer using the same network structure with DnCNN.

For new readers, we recommend they follow the steps below to better understand our model:

• 1. Build conda environment using requirments.txt
• 2. Read & run i2i_nt.ipynb to see how I2I-NT works
• 3. Read d2d_nt.py, then checking its configuration in /options
• 4. Run & check comparation.ipynb to see the results
