Abstract
En 中文
• DDIM-NIR generates high-fidelity NIR spectra for MFH herb identification. • Labeled spectral data from 48 MFH herb species are effectively augmented. • DDIM-NIR outperforms GAN and WGAN-GP in spectral similarity and quality. • 1D-CNN achieves 98.82% accuracy using DDIM-NIR-augmented spectral data. • This work enables robust, small-sample NIR analysis for quality traceability.
