Kernel Reformulation with Deep Constrained Least Squares for Blind Image Super-Resolution
Ziwei Luo;Haibin Huang;Lei Yu;Youwei Li;Bing Zeng;Shuaicheng Liu
IEEE Transactions on Circuits and Systems for Video Technology
Year: 2025 | Early Access Article |
This work proposes to learn blind image super-resolution (SR) using deep constrained least squares deconvolution with low-resolution (LR) space kernels. Our method recovers the high-resolution (HR) image with a kernel estimation step and a kernel-based image restoration process. Specifically, we first reformulate the classical degradation model to transfer the deblurring kernel estimation into the...Show More

Efficient deep learning-based approaches have achieved remarkable performance in single image super-resolution. However, recent studies on efficient super-resolution have mainly focused on reducing the number of parameters and floating-point operations through various network designs. Although these methods can decrease the number of parameters and floating-point operations, they may not necessari...Show More
