A Novel Learnable Interpolation Approach for Scale-Arbitrary Image Super-Resolution

IJCAI 2023poster

Deep convolutional neural networks (CNNs) have achieved unprecedented success in single image super-resolution over the past few years. Meanwhile, there is an increasing demand for single image super-resolution with arbitrary scale factors in real-world scenarios. Many approaches adopt scale-specifi…

Equivalent Transformation and Dual Stream Network Construction for Mobile Image Super-Resolution

CVPR 2023poster

In recent years, there has been an increasing demand for real-time super-resolution networks on mobile devices. To address this issue, many lightweight super-resolution models have been proposed. However, these models still contain time-consuming components that increase inference latency, limiting…

Kernel Estimation and Deconvolution for Blind Image Super-Resolution

ICASSP 2023accepted

Blind super-resolution, different from conventional non-blind super-resolution based on the assumption of fixed degradation, handles various unknown Gaussian blur kernels, and thus is closer to real-world application. The accuracy of kernel estimation and deconvolution directly influences the perfor…
