## NAME

         Find_thinness - determines the thinness ratio of  a  labeled
         binary object

## SYNOPSIS

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

         float Find_thinness(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

         Thinness is a measure of the roundness of  an  object.  Once
         the perimeter(P) and the area(A) of an object are known, the
         thinness(T) is found:
                               T = 4*pi(A/P^2)
         A circle has a thinness ratio of 1.

         This function requires a labeled binary object.
