Module: Eccentricity ()

Description:

For an introduction, see:

Eccentricity is a classical elliptic parameter used on the shape of binarized objects. The eccentricity of an ellipse, usually denoted by , is the ratio of the distance between its two foci to the length of the major axis. The eccentricity is necessarily between 0 and 1; it is zero if and only if a=b, in which case the ellipse is a circle. As the eccentricity tends to 1, the ellipse gets a more elongated shape and tends either towards a line segment (see below) or a parabola, and the ratio a/b tends to infinity :

Ports:

Interpretation

This port specifies whether the input will be interpreted as a 3D volume or a stack of 2D images for processing.

The port is grayed if alternate interpretation is not available.
