A Pathology-Based Machine Learning Method to Assist in Epithelial Dysplasia Diagnosis
Karoline da Rocha, José C. M. Bermudez, Elena R. C. Rivero +1
The Epithelial Dysplasia (ED) is a tissue alteration commonly present in lesions preceding oral cancer, being its presence one of the most important factors in the progression towa…
Fast Unmixing and Change Detection in Multitemporal Hyperspectral Data
Ricardo Augusto Borsoi, Tales Imbiriba, José Carlos Moreira Bermudez +1
Multitemporal spectral unmixing (SU) is a powerful tool to process hyperspectral image (HI) sequences due to its ability to reveal the evolution of materials over time and space in…
Tech Report: A Homogeneity-Based Multiscale Hyperspectral Image Representation for Sparse Spectral Unmixing
L. C. Ayres, S. J. M. de Almeida, J. C. M. Bermudez +1
Several approaches have been proposed to solve the spectral unmixing problem in hyperspectral image analysis. Among them the use of sparse regression techniques aims to characteriz…
Spectral Variability in Hyperspectral Data Unmixing: A Comprehensive Review
Ricardo Augusto Borsoi, Tales Imbiriba, José Carlos Moreira Bermudez +6
The spectral signatures of the materials contained in hyperspectral images, also called endmembers (EM), can be significantly affected by variations in atmospheric, illumination or…
Kalman Filtering and Expectation Maximization for Multitemporal Spectral Unmixing
Ricardo Augusto Borsoi, Tales Imbiriba, Pau Closas +2
The recent evolution of hyperspectral imaging technology and the proliferation of new emerging applications presses for the processing of multiple temporal hyperspectral images. In…
A Blind Multiscale Spatial Regularization Framework for Kernel-based Spectral Unmixing
Ricardo Augusto Borsoi, Tales Imbiriba, José Carlos Moreira Bermudez +1
Introducing spatial prior information in hyperspectral imaging (HSI) analysis has led to an overall improvement of the performance of many HSI methods applied for denoising, classi…
