[Paper]
Well-aligned paired images of Under Display Camera (UDC) include various environments such as day/night, indoor/outdoor, and flares. The light sources (both natural sunlight and artificial light) and different environmental conditions can lead to various forms of degradation. We have incorporated annotations into our dataset to improve the performance of restoration models for UDC image restoration.
Under Display Camera (UDC) faces challenges related to image degradation, including issues such as low transmittance, blur, noise, and flare. Despite its significance, there has been a lack of real-world datasets in the UDC domain. Only synthetic images are available that do not accurately represent real-world degradation. As far as we know, it is the first real-world UDC dataset to overcome the problems of the existing UDC datasets.
You can acquire the download link of our dataset at our Research Group's hompage.
You can download the dataset from the link above. When you conduct training, validation, and inference, just normalize in your PyTorch DataLoader as is generally being done in most image restoration DNN models. We recommend to train your model using .npy format with 4 channels rather than converting it to a 3 channels RGB domain. Note that our dataset is in Low Dynamic Range (LDR). Therefore, you don't have to conduct Reinhard tone-mapping. You can visualize our dataset by running ./dataset/visualize_sit.py, allowing for a visual inspection.
The dataset is created by the authors of the paper as well as the members of the Thunder Research Group at Seoul National University, including Woojin Kim, Gyuseong Lee, Dongyoung Lee, Sangsoo Im, Gwangho Choi, Gyeongje Jo, Yeonkyoung So, Jiheon Seok, Jaehwan Lee, Donghun Choi, and Daeyoung Park, on behalf of universities and research institutions.
