A Novel Spectral–Spatial Classification Method for Hyperspectral Image at Superpixel Level

open access: yesApplied Sciences (Switzerland), 2020
Although superpixel segmentation provides a powerful tool for hyperspectral image (HSI) classification, it is still a challenging problem to classify an HSI at superpixel level because of the characteristics of adaptive size and shape of superpixels ...

Reg-Superpixel Guided Convolutional Neural Network of PolSAR Image Classification Based on Feature Selection and Receptive Field Reconstruction

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023
The convolutional neural network (CNN) has a poor performance in nonuniform and edge regions due to the limitation of fixed receptive field. At the same time, feature stacking of input data can bring burden and overfitting to the network.
