WebIn order to resolve this issue, this paper proposes a novel HVT algorithm based on Pixel-wise Spectral Matching Reduction (PSMR) and Deep Spectral Cascading Texture (Deep-SCT) features. The PSMR is a novel dimensionality reduction method that approximately segments the target and background while compressing the hyperspectral image data. WebJun 20, 2024 · The spectral reduction of hyperspectral data can be done using feature extraction or feature selection. Feature extraction transforms the original data linearly or non-linearly to another feature space to provide a reduced dataset of informative features ( Martinez-Uso et al., 2007 ).
