IRREGULAR_CVIP
irregular_cvip() - calculates the irregularity ratio of a binary object.
Contents
SYNTAX
ir = irregular_cvip(labeledImage, r, c)
Input Parameter include :
- labelImage - Label image of MxN size with single object or multiple objects. Each object has unique gray value.
- r - The row number of a pixel on the object. It is a positive integer.
- c - The column number of a pixel on the object. It is a positive integer.
Output Parameters Include :
- ir - The irregularity ratio of the binary object.
DESCRIPTION
The function calculates the irregularity ratio of the binary objects specified by the row and column inputs given by the user. Irregularity ratio or the compactness ratio of a binary object gives a measure of the irregularity component of the binary object. It is calculated as the inverse of the thinnes ratio of the binary object.
