## CPICANN Datasets

This repository contains the data sets described in the CPICANN paper, available at [GitHub](https://github.com/WPEM/CPICANN).


CPICANN is evaluated on four distinguished datasets, denoted as D1, D2, D3, and D4, with the following characteristics:

- **D1**: 0% background ratio and Gaussian noise (σ=0.25) (v chosen in paper)
- **D2**: 3% background ratio and Gaussian noise (σ=0.25)
- **D3**: 0% background ratio and Gaussian noise (σ=1)
- **D4**: 0% background ratio and Gaussian noise (σ=3)

Contribution and suggestions are always welcome. You can also contact the authors for research collaboration.
