Video Super-Resolution Combining Dual Motion Compensation and Multi-Scale Structure–Texture Prior

Résumé fourni par la source

Video super-resolution methods based on convolutional kernels or optical flow often face challenges such as limited utilization of multi-frame detail information or strong reliance on accurate optical flow estimation. To address these issues, this paper proposes a novel super-resolution reconstruction network named Dual Motion Compensation and Multi-scale Structure–Texture Prior (DCST-Net). Dual motion compensation performs direct and progressive motion mapping in parallel, effectively mitigating estimation bias in motion modeling. A multi-scale structure–texture prior is introduced to enhance high-frequency details through feature fusion, alleviating over-smoothing caused by warping and fusion processes. The proposed DCST-Net method is validated on datasets containing both large and small targets, demonstrating its effectiveness and robustness.
