Towards Real-World Burst Image Super-Resolution: Benchmark and Method

This is the official implementation of ICCV2023 "Towards Real-World Burst Image Super-Resolution: Benchmark and Method".

Here is the [baidu link] (include Cropped RealBSR-RGB), the [baidu link] (include Full-size RealBSR-RGB) and the [google drive link] (include Cropped RealBSR-RGB and Cropped RealBSR-RAW) of the proposed RealBSR dataset. (Please read the folder structure below before using them)

Package dependencies

The project is built with PyTorch 1.10.1, Python3.9, CUDA10.1. For package dependencies, you can install them by:

pip3 install -r requirements.txt

Pretrained model

• Checkpoint of FBANet on RealBSR dataset [Google Drive] and [Baidu Drive Link]

Data preparation

Alignment

For training and testing data of Burst, first you should align the burst frames using homography_alignment.py

python homography_alignment.py

The aligned frames could be put into '../LR_aligned' and then you should use the aligned frames as the input of the following training and testing.

Evaluation

If you want to use your own data, the resolution of data should better >=160x160, and the setting could be changed in ManualDataset.py and test_in_any_resolution.py.

For convenient evaluation, you could use data [here] for evaluation. It is worth noting that the data is not included in training or testing of our BaseModel.

test for arbitrary resolution

python homography_alignment.py
python test_in_any_resolution.py --arch BaseModel --weights ./checkpoints/FAF/model_best.pth --save_images

Training

Base Model

To train BaseModel on RealBSR, we use 2 V100 GPUs and run for 200 epochs:

python3 ./train.py --arch BaseModel --batch_size 16 --gpu '0,1' --train_ps 160 --env 64_0523_MotionMFSR_FAF --embed_dim 64 --warmup
