Frequency Dynamic Convolution for Dense Image Prediction

1 code implementation24 Mar 2025 Linwei Chen, Lin Gu, Liang Li, Chenggang Yan, Ying Fu

In this work, we introduce Frequency Dynamic Convolution (FDConv), a novel approach that mitigates these limitations by learning a fixed parameter budget in the Fourier domain.

Frequency-aware Feature Fusion for Dense Image Prediction

2 code implementations23 Aug 2024 Linwei Chen, Ying Fu, Lin Gu, Chenggang Yan, Tatsuya Harada, Gao Huang

The offset generator refines large inconsistent features and thin boundaries by replacing inconsistent features with more consistent ones through resampling, while the AHPF generator enhances high-frequency detailed boundary information lost during downsampling.

When Semantic Segmentation Meets Frequency Aliasing

1 code implementation14 Mar 2024 Linwei Chen, Lin Gu, Ying Fu

While positively correlated with the proposed aliasing score, three types of hard pixels exhibit different patterns.

Instance Segmentation in the Dark

1 code implementation27 Apr 2023 Linwei Chen, Ying Fu, Kaixuan Wei, Dezhi Zheng, Felix Heide

Existing instance segmentation techniques are primarily tailored for high-visibility inputs, but their performance significantly deteriorates in extremely low-light environments.
