Data cluster analysis-based classification of overlapping nuclei in Pap smear samples

Table 1 Extracted features from detected nuclei regions

1.	Eccentricity*	$\frac{F 1}{a}$
2.	Major axis to minor axis ratio*	$\frac{a}{b}$
3.	Equivalent diameter to actual diameter ratio*	$\frac{\sqrt{4 \frac{Area}{π}}}{\frac{P_{n}}{2 * π}}$
4.	Number of local minima**	–
5.	Max distance between local minima**	–

^*a,b and F1 are given in Figure 4e. P _n= number of pixels in perimeter. **Extraction process is given in text.
