Building Segmentation Based on Deep Feature Extraction and Multi Output Enhancement Fusion
This paper proposes a deep feature extraction and multi output enhanced building semantic segmentation network to address the problem of missing individual building parts and similar texture non building misclassification in high-resolution remote sensing image building semantic segmentation.Firstly,a parallel continuous void spatial attention pyramid module is designed at the alternation of encoding and decoding to achieve deep extraction of high-dimensional features of buildings.Then,in the network decoding stage,a multi-output enhanced fusion module is designed to improve the effective participation of building features at different scales in the output results.Selecting the similar algorithms of U-Net,DeeplabV3+,MA-FCN and BRRNet for comparison and testing on the public datasets of Massachusetts and WHU,the OA,precision,recall,F1 and IoU indicators can reach 98.87%,94.53%,95.40%,90.41%,and 94.96%,respectively.OA,F1,recall and IoU accuracy are higher than that of the other four indicators.The OA,precision,recall,IoU and F1 of the proposed method are higher than that of U-Net by 0.25%,1.12%,1.14%,2.02%,and 1.12%,respectively.
