Semantic segmentation of high-resolution remote sensing images using self-attention mechanism
摘要
Abstract
To address the challenges of of multiscale feature extraction and insufficient utilization of context infor-mation in remote sensing images,this paper presents a linear multihead self-attention network model.The model combines a self-attention mechanism with depthwise separable convolution,specifically designed for the semantic segmentation of high-resolution remote sensing images.A depthwise separable convolution module,which reduces computational load and facilitates local feature extraction,is initially introduced.Then,a linear multihead self-at-tention module is proposed in the encoder branch to reduce complexity.Finally,a decoder is designed to restore the resolution of the feature map and integrate multilevel features through a cascade operation,generating high-reso-lution semantic segmentation results.The proposed method achieves mF1 scores of 90.77%and 92.36%on the IS-PRS Vaihingen and Potsdam datasets,respectively.Compared with current mainstream algorithms,the segmenta-tion accuracy and overall accuracy of impervious surfaces,buildings,low vegetation,and trees are improved.The proposed linear multihead self-attention network is an efficient semantic segmentation model for high-resolution re-mote sensing images.关键词
