Table 1 Overlap ratio between results of manual and automatic segmentation. While in the manual detection, folds were identified by referring to the RGB color image of the tissue slide, the numerical feature calculated from the difference between the luminance of the enhanced and original images served as features in the automatic fold detection. The low values of the overlap ratio might have been caused by mislabeling of image pixels or undetected tissue folds in the manual segmentation
