Hyperspectral Imaging
A technique that acquires images across tens to hundreds of contiguous narrow spectral bands, thereby capturing the spectral information of a target. It is widely used in remote sensing, agriculture, and medicine.
Timeline (last 90 days)
In scientific imaging, modalities such as hyperspectral imaging (HSI) and magnetic resonance imaging (MRI) are difficult to obtain with clean training labels at scale, which limits the application of traditional supervised learning approaches.
Hyperspectral imaging collects data over hundreds of contiguous narrow bands, a single data cube is far larger in volume than an ordinary RGB image, and adjacent bands are highly correlated; in real scenarios there is no noise-free hyperspectral reference, so supervision signals can usually only be constructed by synthetic noise or physical simulation.
