Figure 6
Mean transmittance of the TNM-classification (A–C) and grading (D) in stroma (first column) and EAC cells (second column). The achieved accuracy and the applied classification algorithm is shown under the spectra. The red rectangle shows the areas of high differences of the spectra. (A) The mean transmittance of stroma depicts high difference in the range from 525 nm to 575 nm in case of T-category only. (B) The mean transmittance of stroma reveals high variance in the range from 525 nm to 575 nm in case of the N-category. (C) The mean transmittance of stroma showed high variance in the range from 525 nm to 575 nm and in the range from 625 nm to 675 nm in case of the N-category. (D) The mean transmittance of stroma demonstrated high variance in the range from 525 nm to 575 nm and in the range from 625 nm to 675 nm in case of the N-category. The classification results for the gradings was less than 48% accuracy.
