Heunseung Lim, Jungkyoo Shin, Hyoungki Choi, Dohoon Kim, Eunwoo Kim, and Joonki Paik. 2024 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)

Requirements

• Python 3.8
• PyTorch 1.9.1
• MATLAB (for data preparation)

Usage

Data preparation

1. Download data from [dataset]
2. Create data using the Matlab executable located in './GeneralH5Data/PrepareData.m'. AHDR) *(GenerH5data folders from AHDR)

Testing

1. Install this repository and the required packages. A pretrained model is in ./trained-model.
2. Prepare dataset.
   1. Download from [dataset]
   2. Import and test the image based on the file in the test-flow.txt file.
   3. Create and test a testing file using the file in the AHDR) Github link './GeneralH5Data/PrepareData.m'
3. Run python script_testing.py files.

Training

1. Prepare dataset.

2. Download dataset.
3. Similar to testing, create training-only data and learn using the 'script_training.py' file. Hyperparameters must be adjusted.

Pre-trained model download (.pkl)
