🔍Dataset

We proposed two datasets iSAID-dark and darkrs. Please click ISAID and darkrs for detailed preparation description.

Fig. 2. Samples from the proposed iSAID-dark(Up) and darkrs(Down) dataset.

Training & Testing

python test.py

🔍Visual Results

Fig. 3. The visualization results on the iSAID-dark dataset. We present the histogram of color distribution for the images. The histograms placed in Input/GT represent the color distribution of the GT. It can be observed that our method’s histogram is closer to the GT histogram.

Fig. 4. The visualization results on the DICM dataset (top) and the NPE dataset (bottom).
