🚀 This is the official repository of HDR-BiTNet (TMM 2023).

HDR-BiTNet aims at addressing the practical translation between UHD-HDR (HDRTV) and HD-SDR (SDRTV) videos.

We provide the training and test code along with the trained weights and the dataset (train+test) used for the HDR-BiTNet.

❤️ If you find this repository useful, please star this repo 🌟 and cite our paper 📄.

Video example

⚠️ Note: This GIF file has been tone-mapped to SDR and compressed for visibility.

See more comparison of SDR video and HDR video in example/ folder.

Note: The HDR file in example/ is encoded to comply with the HDR10 standard. For the best viewing experience, please watch the video on certified HDR displays with maximum brightness. Alternatively, a Mac Book Pro can be used for convenience.

Test code

Quick Start

1. Download the test dataset from this link.
2. Unzip and place the 'test' dataset in a proper folder, e.g., /testdata.
3. Put the pretrained model file (./model.pth) in a proper folder.
4. Set a config file in options/test/, then run as following:

python test.py -opt options/test/test.yml

Code Framework

The code framework follows BasicSR.

Contents

Config: options/ Configure the options for data loader, network structure, model, training strategies and etc.

Data: data/ A data loader to provide data for training, validation and testing.

Model: models/ Construct models for training and testing.

Network: models/modules/ Construct network architectures.
