A standardised protocol for texture feature analysis of endoscopic images in gynaecological cancer

Table 3 MSE for three experiments for uncorrected (first column) and gamma corrected (second column) using the median values of the endoscopy output image before and after calibration (for calibrated targets)

MSE for each Channel
Channels	$M S E_{o r g - c a m} = \frac{1}{N M} \sum_{i, j = 1}^{N, M} {(I_{o r g_{i, j}} - I_{c a m e r a_{i, j}})}^{2}$	$M S E_{o r g - c o r} = \frac{1}{N M} \sum_{i, j = 1}^{N, M} {(I_{o r g_{i, j}} - I_{c o r_{i, j}})}^{2}$
