PolSAR Image Classification Using a Superpixel-Based Composite Kernel and Elastic Net
Published 2021-01-01“…To this end, this paper presents a composite kernel-based elastic net classifier (CK-ENC) for better PolSAR image classification. First, based on superpixel segmentation of different scales, three types of features are extracted to consider more discriminative information, thereby effectively suppressing the interference of speckles and achieving better target contour preservation. …”

Unsupervised change detection in PolSAR images using siamese encoder–decoder framework based on graph-context attention network
Published 2023-11-01“…The GCA-SEDN can mine local and global polarization features simultaneously. Firstly, based on the local features extracted by CNN, the feature optimization graph attention (FOGA) module is constructed to capture global features of PolSAR images. …”

Research on the 3D Fine Modeling Method of In-Service Road
Published 2023-01-01“…To achieve the digitization of all traffic infrastructure elements and enable three-dimensional digital representation of physical facilities, a multilevel road three-dimensional reverse modeling method is proposed based on road point cloud data obtained by a vehicle laser scanning system. First, based on the distribution characteristics of each target structure in the road scene and the modeling requirements, a levels of detail (LOD) modeling specification is designed, and the required feature data format for each level is defined. …”
