Enhancing Hyperspectral Images via Diffusion Model and Group-Autoencoder Super-resolution Network

1 code implementation27 Feb 2024 Zhaoyang Wang, Dongyang Li, Mingyang Zhang, Hao Luo, Maoguo Gong

Existing hyperspectral image (HSI) super-resolution (SR) methods struggle to effectively capture the complex spectral-spatial relationships and low-level details, while diffusion models represent a promising generative model known for their exceptional performance in modeling complex relations and learning high and low-level visual features.
