Abstract

 Existing real-time semantic segmentation models have achieved notable progress. However, they still suffer from feature redundancy and insufficient capability in capturing spatial details. To address these issues, this paper proposes a real-time semantic segmentation network based on selective state models and frequency-domain spatial detail enhancement. Specifically, a Selective Redundancy Suppression Module (SRSM) is designed based on a selective scanning mechanism. This module retains informative features while suppressing redundant ones through selective scanning. In addition, a Frequency Edge Enhancement Module (FEEM) is constructed. It combines the Fast Fourier Transform (FFT) with an attention mechanism to enhance high-frequency edge information. SFENet is evaluated on two datasets. On the Cityscapes dataset, it achieves 77.3% mIoU, outperforming the baseline by 1.4% mIoU. On the CamVid dataset, it achieves 77.1% mIoU. Experimental results demonstrate that SFENet effectively preserves critical semantic features and accurately segments object boundaries.
