## NAME

         Find_irregular - determines the irregularity  of  a  labeled
         binary object

## SYNOPSIS

          #include <CVIPimage.h>
          #include <CVIPmatrix.h>
          #include <CVIPfeatures.h>
          #include <CVIPdef.h>

         float Find_irregular(Image *inputImage, int gray_level)

          <inputImage> - a pointer to an Image structure
          <gray_level> - the gray value of the labeled object

## PATH

          $CVIPHOME/FEATURE/thiness.c

## DESCRIPTION

         Irregularity is a measure of the regularity  of  an  object.
         Once  the  perimeter(P)  and  the  area(A)  of an object are
         known, the irregularity(I) is found:
                               I = (P^2/4*pi*A)
         Irregularity is the inverse of thinness.

         This function requires a labeled binary object.
