In this paper, a source component-based anomaly detection approach is proposed. It first extracts the source components in the spectral image data cube by using ...
In this work, we presented an approach that combines source component extraction by unmixing and anomaly components identification by volume and sparsity ...
TL;DR: A novel low rank anomaly detection algorithm in hyperspectral images (HSI), where three components are involved, that constantly achieves high detection ...
Sep 13, 2024 · This model organically combines sparse representation with low-rank representation in order to effectively depict the intricate background ...
The anomaly part was constrained by column sparsity simultaneously due to the global sparsity of anomalous targets in hyperspectral images. To further clarify ...
In this paper, we developed a signal decomposition approach for the purpose of anomaly detection based on the idea of low rank and sparse decomposition taking ...
Sep 8, 2021 · To detect anomalies with RPCA, anomalies are modeled by the sparse component and background is modeled by the low-rank component, and the ...
