Classification features and their descriptions.

Feature	Description
Mass (g)	The mass of the eggs. Mass is scaled with 1-g sensitive digital scale
Short axis (mm)	Minor axis of the egg. The short axis is measured with a 0.01 mm sensitive digital caliper. (|CD| on Fig. 3)
Long axis (mm)	Major axis of the egg. The long axis is measured with a 0.01 mm sensitive digital caliper. (|AB| on Fig. 3)
Foci (mm)	The distance between the rounded side of egg and where the rear side touches to the caliper. (|AE| on Fig. 3)
Shape index	Physical measured short and long axis ratio (|CD|/|AB|)
Automatic eccentricity	Eccentricity value which is taken from MATLAB regionprops
Automatic SI	Shape Index value which is the rate of MATLAB short and long axis
Ovality	The ratio between foci and long axis, measured physically. (|AE|/|AB)|
