Event-guided Multi-patch Network with Self-supervision for Non-uniform Motion Deblurring

1 code implementation14 Feb 2023 Hongguang Zhang, Limeng Zhang, Yuchao Dai, Hongdong Li, Piotr Koniusz

Contemporary deep learning multi-scale deblurring models suffer from many issues: 1) They perform poorly on non-uniformly blurred images/videos; 2) Simply increasing the model depth with finer-scale levels cannot improve deblurring; 3) Individual RGB frames contain a limited motion information for deblurring; 4) Previous models have a limited robustness to spatial transformations and noise.

SeqXFilter: A Memory-efficient Denoising Filter for Dynamic Vision Sensors

no code implementations2 Jun 2020 Shasha Guo, Lei Wang, Xiaofan Chen, Limeng Zhang, Ziyang Kang, Weixia Xu

We not only give the visual denoising effect of the filter but also use two metrics for quantitatively analyzing the filter's performance.

A Noise Filter for Dynamic Vision Sensors using Self-adjusting Threshold

no code implementations8 Apr 2020 Shasha Guo, Ziyang Kang, Lei Wang, Limeng Zhang, Xiaofan Chen, Shiming Li, Weixia Xu

Neuromorphic event-based dynamic vision sensors (DVS) have much faster sampling rates and a higher dynamic range than frame-based imagers.
