Building extraction method based on MFF-Deeplab v3+network for high-resolution remote sensing images
Automatic extraction of building information from high-resolution remote sensing images is of great significance in the fields of environmental monitoring,earthquake mitigation,and land use,making it a research hotspot in the field of high-resolution remote sensing applications.In order to improve the accuracy of building extraction from high-resolution remote sensing images,a building extraction method based on MFF-Deeplabv3+(multiscale feature fusion-Deeplabv3+)network for high-resolution remote sensing images is proposed in this paper.First,the multi-scale feature enhancement module is designed to enable the network to capture more scale context information;then,the feature fusion module is designed to effectively fuse deep features with shallow features to reduce the loss of detail information;finally,the attention mechanism module is introduced to select accurate features adaptively.In the comparison experiments of the Inria building dataset,MFF-Deeplabv3+achieved the highest accuracy in PA,MPA,FWIoU,and MIoU metrics with 95.75%,91.22%,92.12%,and 85.01%,respectively,while the generalization experiments of the WHU building dataset achieved good results.The results show that this method extracts building information from high-resolution remote sensing images with high accuracy and strong generalization.
