Dual-domain difference and scale selection enhancement for remote sensing image change detection
摘要
Abstract
In remote sensing image change detection,continuous downsampling often results in severe information loss and pseudo-change interference.To address these issues,we propose the dual-domain difference and scale selection enhance change detection network(DDSE-Net),which is built upon a dual-branch encoder and U-Net architecture.The proposed framework incorporates three key innovations:(1)A dual-domain joint difference enhancement module(DJEM),which first employs channel attention to strengthen difference representations along the channel dimension,and further integrates wavelet transform with spatial attention to achieve dual-domain enhancement in both spatial and frequency domains.This design effectively emphasizes true change information while suppressing pseudo changes.(2)A scale selection enhancement downsampling module(SEDM),which captures multi-scale features through convolution and pooling operations of varying receptive fields during the downsampling process.The extracted features are subsequently refined with spatial and channel attention,thereby alleviating information loss.(3)A gated difference perception module(GDPM),which introduces a gating mechanism to adaptively weight and fuse multi-scale change features,enabling more comprehensive integration and enhancing the network's multi-scale representation capability.The proposed DDSE-Net achieves F1-score improvements of at least 4.48%,2.18%,and 1.16%on the WHU,Google,and LEVIR datasets,respectively,compared with eight mainstream change detection networks,including FC-EF,FC-Conc,IFN,SNUNet,BIT,MSCANet,LightCDNet,and STADE-CDNet,demonstrating the effectiveness of DDSE-Net.关键词
