NAME
MorphOpen_Image - performs morphological opening
SYNOPSIS
#include "CVIPimage.h"
#include "CVIPtoolkit.h"
#include "CVIPmatrix.h"
#include "CVIPmorph.h"
Image *MorphOpen_Image(Image *imageP, Matrix *kernelP,
CVIP_BOOLEAN user_org, int row, int col)
<inputImage> - a pointer to an Image structure
<kernelP> - a pointer to a Matrix structure
<user_org> - define center of kernel
<row> - user-defined row of kernel center
<col> - user-defined column of kernel center
Image *MorphOpen(Image *inputImage, int k_type, int ksize,
int height, int width)
<inputImage> - pointer to an Input
<k_type> - kernel type (1=disk 2=square 3=rectangle
4=cross)
<ksize> - kernel size (height and width of mask)
<height> height for square and rectangle, thickness of
lines for cross
<width> - width for rectangle, size of cross

DESCRIPTION
Morphologic opening consists of morphological erosion fol-
lowed by morphological dilation of an image. It is often
used to eliminate small objects from an image.
