Classification Endmember Selection with Multi-Temporal Hyperspectral Data

open access: yesRemote Sensing, 2020
In hyperspectral image classification, so-called spectral endmembers are used as reference data. These endmembers are either extracted from an image or taken from another source.

A CNN with noise inclined module and denoise framework for hyperspectral image classification

open access: yesIET Image Processing, 2023
Deep Neural Networks have been successfully applied in hyperspectral image classification. However, most of prior works adopt general deep architectures while ignore the intrinsic structure of the hyperspectral image, such as the physical noise ...

Wavelet based segmentation of hyperspectral colon tissue imagery [PDF]

open access: yes, 2003
Segmentation is an early stage for the automated classification of tissue cells between normal and malignant types. We present an algorithm for unsupervised segmentation of images of hyperspectral human colon tissue cells into their constituent parts by ...

Deep Manifold Embedding for Hyperspectral Image Classification [PDF]

open access: yesIEEE Transactions on Cybernetics, 2022
Deep learning methods have played a more and more important role in hyperspectral image classification. However, the general deep learning methods mainly take advantage of the information of sample itself or the pairwise information between samples while ignore the intrinsic data structure within the whole data.

Texture Based Hyperspectral Image Classification [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2014
Abstract. This research work presents a supervised classification framework for hyperspectral data that takes into account both spectral and spatial information. Texture analysis is performed to model spatial characteristics that provides additional information, which is used along with rich spectral measurements for better classification of ...

Adaptive Markov random fields for joint unmixing and segmentation of hyperspectral image [PDF]

open access: yes, 2013
Linear spectral unmixing is a challenging problem in hyperspectral imaging that consists of decomposing an observed pixel into a linear combination of pure spectra (or endmembers) with their corresponding proportions (or abundances). Endmember extraction

SpectralFormer: Rethinking Hyperspectral Image Classification With Transformers [PDF]

open access: yesIEEE Transactions on Geoscience and Remote Sensing, 2022
Hyperspectral (HS) images are characterized by approximately contiguous spectral information, enabling the fine identification of materials by capturing subtle spectral discrepancies. Owing to their excellent locally contextual modeling ability, convolutional neural networks (CNNs) have been proven to be a powerful feature extractor in HS image ...
