NTIRE (New Trends in Image Restoration and Enhancement) is a premier conference focused on advancing image processing technologies. Researchers compete in challenges like low-light enhancement, motion blur removal, and hyperspectral restoration. Below are key highlights and practical implementations.
You Should Know:
1. Retinexformer – Low-Light Image Enhancement
Retinexformer, a lightweight transformer-based model, achieved 2nd place in NTIRE 2024. It processes 6K images in ~0.5s on an RTX 3090 with only 1.6M parameters.
How to Run Retinexformer:
git clone https://github.com/xxx/Retinexformer.git cd Retinexformer pip install -r requirements.txt python demo.py --input_path dark_image.jpg --output_path enhanced_image.jpg
Key Commands:
- Use `nvidia-smi` to monitor GPU usage.
- Optimize with `torch.jit.script` for faster inference.
2. DeblurGANv2 – Motion Blur Removal
Winner of NTIRE 2021, DeblurGANv2 processes UAV-captured wind turbine images in ~0.19s per image.
DeblurGANv2 Implementation:
wget https://github.com/xxx/DeblurGANv2/releases/download/v1.0/model.h5 python deblur_image.py --model model.h5 --input blurred.jpg --output sharp.jpg
Useful Commands:
– `ffmpeg -i input.mp4 -vf “unsharp=5:5:1.0” output.mp4` (Quick sharpening alternative).
– `exiftool` to verify metadata post-processing.
3. MST++ – Hyperspectral Image Prediction
MST++ (2022 winner) predicts IR spectra from RGB images with 99.93% accuracy.
MST++ Setup:
conda create -n mstpp python=3.8 conda activate mstpp pip install torch torchvision spectral python predict_ir.py --rgb input_rgb.png --output ir_prediction.hdr
Key Tools:
- ENVI for hyperspectral analysis.
- ImageMagick (
convert input.png -colorspace Gray output.png) for preprocessing.
What Undercode Say
NTIRE’s breakthroughs push real-world applications—forensics, drone inspections, and night vision. Retinexformer’s efficiency makes it deployable on edge devices, while DeblurGANv2 aids industrial inspections. MST++ bridges RGB and hyperspectral imaging, revolutionizing forensic analysis.
Expected Output:
- Enhanced low-light images (
enhanced_image.jpg). - Deblurred UAV footage (

ir_prediction.hdr).
Prediction
Hyperspectral imaging will become mainstream in surveillance, while lightweight transformers like Retinexformer will dominate mobile AI processing.
