I want to run a c program in visual basic. How can I do this? Actually this program is for wiener filtering. I want to change the parameter of K in visual basic and want to see the different image output. For your information I use mvc++6.
Thanks in advance.

code is given for your understanding.
- Code: Select all
/* Wiener filter - restoration using only non-zero PSF values */
#define MAX
#include "fftlib.h"
int
main (int argc, char *argv[])
{
int n=0, nr, nc;
IMAGE im1, p;
COMPLEX_IMAGE fft1, fft2;
float x, xi, H, K, t;
int i,j, k;
printf ("Image Restoration System module 5 - Weiner filter\n");
/* Try to open standard image files. */
if (argc < 4)
{
printf ("WEINER input psf output\n\n");
exit (0);
}
im1 = Input_PBM (argv[1]);
if (im1 == 0)
{
printf ("No such file as '%s'\n", argv[1]);
exit(1);
}
p = Input_PBM (argv[2]);
if (p == 0)
{
printf ("No such file as '%s'\n", argv[2]);
exit(1);
}
if (im1->info->nr != im1->info->nc)
{
printf ("Input image is not square. Use ALIGN.\n");
exit(0);
}
if (p->info->nr != p->info->nc)
{
printf ("PSF image is not square. Use ALIGN.\n");
exit(0);
}
if (im1->info->nr != p->info->nr)
{
printf ("Input and PSF images differ in size.\n");
exit (0);
}
nr = im1->info->nr; nc = im1->info->nc;
printf("The number of rows of the image:%d\n", nr);
printf("The number of columns of the image:%d\n", nc);
image_fftoc (im1, &fft1);
normalize_set ();
image_fftoc (p, &fft2);
normalize_clear();
printf ("Enter K: ");
scanf ("%f", &K);
for (i=0; i<nr; i++)
for (j=0; j<nc; j++)
{
x = fft2[i][j]; xi = fft2[i][j+nc];
H = pix_cnorm (x, xi);
if (H == 0.0)
{
fft1[i][j] = fft1[i][j+n] = 0.0;
continue;
}
t = H/(H+K);
cdiv (t, 0.0, &x, &xi);
cprod (fft1[i][j], fft1[i][j+nc], &x, &xi);
fft1[i][j] = x; fft1[i][j+nc] = xi;
}
freecomplex (fft2); fft2 = (COMPLEX_IMAGE)0;
image_fftinvoc (fft1, &fft2);
freecomplex (fft1); fft1 = (COMPLEX_IMAGE)0;
filt_toint (fft2, p, 0);
Output_PBM (p, argv[3]);
}
