A Multi-Branch Feature Fusion Strategy Based on an Attention Mechanism for Remote Sensing Image Scene Classification

Abstract: In recent years, with the rapid development of computer vision, increasing attention has been paid to remote sensing image scene classification. To improve the classification performance, many studies have increased the depth of convolutional neural networks (CNNs) and expanded the width of the network to extract more deep features, thereby increasing the complexity of the model. To solve this problem, in this paper, we propose a lightweight convolutional neural network based on attention-oriented multi-branch… Show more

“…To demonstrate the superiority of our proposed method, it is compared with other methods on UCM, including Bidirectional adaptive feature fusion method (BDFF method) [25], Multiscale CNN (MCNN) [37], ResNet with weighted spatial pyramid matching collaborative representation-based classification (ResNet with WSPM-CRC) [38], VGG16 with multi-layer stacked covariance pooling (VGG16 with MSCP) [26], Gated bidirectional network (GBNet) [29], Feature aggregation CNN (FACNN) [39], Scale-free CNN (SF-CNN) [40], Deep discriminative representation learning with attention map method (DDRL-AM method) [41], and CNN based on attention-oriented multi-branch feature fusion (AMB-CNN) [42]. The training ratio of 80% is used on this dataset, and OA is taken as the evaluation index.…”
