Welcome to the exciting world of image processing! In this article, we’ll explore the incredible capabilities of the Blur Interpolation Transformer (BiT) introduced in the CVPR 2023 paper by Zhihang Zhong and his fellow researchers. This powerful transformer-based technique takes on the complex task of arbitrary factor blur interpolation.
Overview of BiT
Imagine trying to clean up a blurry photograph. Using traditional methods might leave you frustrated; however, with BiT, it’s like having a skilled artist sharpen those image details for you! This innovative model not only performs outstanding interpolation but also comes with a dedicated real-world dataset for benchmarking.
Getting Started
To dive into the world of BiT, you’ll need to prepare your environment. Below, we break down the steps to install the necessary dependencies and datasets.
Downloading the Required Data
- Download the synthesized Adobe240 dataset from their original repo.
- Our real-world dataset RBI can be downloaded from here.
Setting Up Your Conda Environment
Now that you have the data, let’s set up your development environment with Conda:
conda create -n BiT python=3.8
conda activate BiT
pip install torch==1.12.1+cu116 torchvision==0.13.1+cu116 torchaudio==0.12.1 --extra-index-url https://download.pytorch.org/whl/cu116
pip install -r requirements.txt
Training BiT
Training BiT is straightforward, but let’s think of it as training a puppy to perform a trick. We want to feed it the right commands (data) repeatedly until it learns how to perform accurately.
Training on Adobe240
python -m torch.distributed.launch --nproc_per_node=8 train_bit.py --config .configs/bit_adobe240.yaml
Training on RBI
python -m torch.distributed.launch --nproc_per_node=8 train_bit.py --config .configs/bit_rbi.yaml
Testing Your Model
After training, it’s time to test the effectiveness of your model. Just like a new invention that needs to be showcased, you’ll want to push your model through its paces.
Testing on Adobe240
CUDA_VISIBLE_DEVICES=0 .tools/test/test_bit_adobe240.sh .checkpoints/bit++_adobe240/cfg.yaml .checkpoints/bit++_adobe240/latest.ckpt .results/bit++_adobe240/home/zhong/Dataset/Adobe_240fps_dataset/Adobe_240fps_blur
Testing on RBI
CUDA_VISIBLE_DEVICES=0 .tools/test/test_bit_rbi.sh .checkpoints/bit++_rbi/cfg.yaml .checkpoints/bit++_rbi/latest.ckpt .results/bit++_rbi
Performing Inference
If you want to see the magic of BiT in action with new images, run the inference command:
sh .tools/inference/inference.sh .checkpoints/bit++_adobe240/cfg.yaml .checkpoints/bit++_adobe240/latest.ckpt .demo/00777.png .demo/00785.png .demo/00793.png .demo/bit++_results
Troubleshooting Tips
If you encounter any issues during installation, training, or testing, here are some pointers to help you:
- Ensure all required packages are installed correctly. Use the latest versions listed in the requirements.
- Check for any typos in your config file paths or command lines.
- Make sure your GPU is correctly set up and recognized by the system.
