HyperDID: Hyperspectral Intrinsic Image Decomposition With Deep Feature Embedding

The dissection of hyperspectral images (HSIs) into intrinsic components through hyperspectral intrinsic image decomposition (HIID) enhances the interpretability of hyperspectral data, providing a foundation for more accurate classification outcomes. However, the classification performance of HIID is constrained by the model’s representational ability. To address this limitation, this study rethinks HIID for classification tasks by introducing deep feature embedding. The proposed framework, HyperDID, incorporates the environmental feature module (EFM) and categorical feature module (CFM) to extract intrinsic features. In addition, a feature discrimination module (FDM) is introduced to separate environment-related and category-related features. Experimental results across three commonly used datasets validate the effectiveness of HyperDID in improving HSI classification performance. This novel approach holds promise for advancing the capabilities of HSI analysis by leveraging deep feature embedding principles. The implementation of the proposed method can be accessed soon at https://github.com/shendu-sw/HyperDID for the sake of reproducibility.
