tively). The second and third lines describe how many
images were best segmentated with 2 and 3 thresh-
olds respectively. The other three lines describe how
many images where best segmentated with 1,2 and 3
thresholds respectively with the FF and BF methods
resulting in the same thresholds amount.
From Table 2, it is possible to reaffirm the obser-
vations made from Fig. 3, that generally, 3 thresh-
olds produce a better segmentation than 2 which,
in turn, is still better than 1 threshold (binariza-
tion). This can be explained due to the matrix nor-
malization. The brighter the M
i,j
cell, the closer the
j-eth threshold segmentation is to the ...
