Separating Surface Reflectance from Volume Reflectance in Medical Hyperspectral Imaging [PDF]

open access: yesDiagnostics
Hyperspectral imaging has shown great promise for diagnostic applications, particularly in cancer surgery. However, non-bulk tissue-related spectral variations complicate the data analysis. Common techniques, such as standard normal variate normalization,
