Classification of hyperspectral images for detection of hepatic carcinoma cells based on spectral–spatial features of nucleus [PDF]

open access: yesJournal of Innovative Optical Health Sciences, 2020
A distinguishing characteristic of normal and cancer cells is the difference in their nuclear chromatin content and distribution. This difference can be revealed by the transmission spectra of nuclei stained with a pH-sensitive stain.
