Spatial and Spatial-Spectral Morphological Mamba for Hyperspectral Image Classification

2 code implementations2 Aug 2024 Muhammad Ahmad, Muhammad Hassaan Farooq Butt, Adil Mehmood Khan, Manuel Mazzara, Salvatore Distefano, Muhammad Usama, Swalpa Kumar Roy, Jocelyn Chanussot, Danfeng Hong

To address these challenges, we propose the morphological spatial mamba (SMM) and morphological spatial-spectral Mamba (SSMM) model (MorpMamba), which combines the strengths of morphological operations and the state space model framework, offering a more computationally efficient alternative to transformers.

3D/2D regularized CNN feature hierarchy for Hyperspectral image classification

no code implementations25 Apr 2021 Muhammad Ahmad, Manuel Mazzara, Salvatore Distefano

Convolutional Neural Networks (CNN) have been rigorously studied for Hyperspectral Image Classification (HSIC) and are known to be effective in exploiting joint spatial-spectral information with the expense of lower generalization performance and learning speed due to the hard labels and non-uniform distribution over labels.
