Graph of changes in the surface area A ( p w ) for different binarization thresholds p w . The colours indicate characteristic areas: blue refers to the area of too low threshold value (the object surface is too small), green highlights the area of changes in binarization threshold giving the best segmentation results whereas red indicates too high binarization threshold (the resultant segmented object is too large).
