Researchers from Samsung Advanced Institute of Technology and KAIST developed an efficient blind motion deblurring method called "blur pixel discretization." This approach categorizes blur patterns at the pixel level before applying a continuous correction to the image, achieving high-quality deblurring with significantly reduced computational requirements. The method demonstrates comparable or better performance than state-of-the-art models while using up to 10x fewer operations, making it suitable for resource-constrained devices like smartphones.
Key insights
- Decomposing the complex deblurring problem into discrete blur classification followed by continuous residual correction significantly improves efficiency and accuracy.
- Learning pixel-level blur categories (a blur segmentation map) provides a robust guide for the deblurring process, particularly for non-uniform and large motion blur.
- Predicting the image residual error rather than the entire sharp image enables a more efficient network and helps preserve original image content.
