# LERSGAN_RS_PAPER

Paper-structured LersGAN dataset rebuild for low-light remote sensing image enhancement.

## Dataset Description

This dataset follows the dataset protocol described in the paper's dataset section. The training and validation splits are unpaired low-light and normal-light image pools. The test split contains paired normal-light remote-sensing images and two generated low-light sets:

- `RSDark1`: standard low-light degradation with brightness scaling alpha in `[0.2, 0.4]` plus Gaussian sensor noise.
- `RSDark2`: extreme low-light degradation with brightness scaling alpha in `[0.05, 0.2]` plus Poisson-style shot noise and Gaussian read noise.

The paper reports aggregate selected counts, not exact per-source selected file lists. This rebuild records the available local reconstruction and is intended for LersGAN reproduction experiments.
