Degradation-Aware Self-Attention Based Transformer for Blind Image Super-Resolution

1 code implementation6 Oct 2023 Qingguo Liu, Pan Gao, Kang Han, Ningzhong Liu, Wei Xiang

In particular, we integrate both CNN and Transformer components into the SR network, where we first use the CNN modulated by the degradation information to extract local features, and then employ the degradation-aware Transformer to extract global semantic features.

A lightweight multi-scale context network for salient object detection in optical remote sensing images

1 code implementation18 May 2022 Yuhan Lin, Han Sun, Ningzhong Liu, Yetong Bian, Jun Cen, Huiyu Zhou

Meanwhile, in order to accurately detect complete salient objects in complex backgrounds, we design an attention-based pyramid feature aggregation mechanism for gradually aggregating and refining the salient regions from the multi-scale context extraction module.
