Spatial-Spectral Hyperspectral Classification based on Learnable 3D Group Convolution

1 code implementation15 Jul 2023 Guandong Li, Mengxia Ye

Deep neural networks have faced many problems in hyperspectral image classification, including the ineffective utilization of spectral-spatial joint information and the problems of gradient vanishing and overfitting that arise with increasing depth.

Hyperspectral Image Classification

Faster hyperspectral image classification based on selective kernel mechanism using deep convolutional networks

1 code implementation14 Feb 2022 Guandong Li, Chunju Zhang

Using 3D-CNN can simultaneously acquire features of spatial and spectral dimensions to facilitate classification of features, but hyperspectral image information spectral dimensional information redundancy.
