Fig. 3: Spectral characterization of TT, NT, and BV classes and their relationship with HbO2 and deoxyHb.
From: Hyperspectral imaging benchmark based on machine learning for intraoperative brain tumour detection
Mean absorbance values of the entire labelled dataset separated by classes (solid lines) after applying a basic pre-processing (calibration, extreme band noise removal, and noise filtering) and molar extinction spectra (dashed lines) of HbO2 and deoxyHb. a TT class between 440 and 650 nm. b TT class between 650 and 910 nm. c NT class between 440 and 650 nm d NT class between 650 and 910 nm. e BV class between 440 and 650 nm. f BV class between 650 and 910 nm.
