Use of sliders in OpenCV

There are two different kinds of smoothing types in the image. One is color image, and the other is grayscale image. It has been proved that both types can


#include <cv.h>
#include #include <cxcore.h>


int param1=1;
int param2=1;
Iplimage *img;
Iplimage *image;
Iplimage *DST;


void Switch_callback (int position)
{
int m_param1=param1*2+1;
int m_param2=param2*2+1; Mask size must be an odd number greater than or equal to 1


Cvsmooth (IMAGE,DST,CV_GAUSSIAN,M_PARAM1,M_PARAM2);

Cvsmooth (IMG,DST,CV_GAUSSIAN,M_PARAM1,M_PARAM2);

Cvshowimage ("Smooth Demo", DST);
}


void Main ()
{img=cvloadimage ("2.bmp", 1);


Image=cvcreateimage (Cvgetsize (IMG), ipl_depth_8u,1); Here is the conversion of grayscale images. Then Gaussian smoothing for grayscale images
Dst=cvcreateimage (Cvgetsize (IMG), ipl_depth_8u,1);
Cvcvtcolor (Img,image,cv_bgr2gray);



Dst=cvcreateimage (Cvgetsize (IMG), ipl_depth_8u,3); Gaussian smoothing of images directly for color images



Cvnamedwindow ("Smooth Demo", 1);

Cvcreatetrackbar ("Param1", "Smooth Demo", &param1,99,switch_callback);
Cvcreatetrackbar ("Param2", "Smooth Demo", &param2,99,switch_callback);


while (1)
{
if (Cvwaitkey (15) ==27)
Break
}
Cvreleaseimage (&AMP;IMG);
Cvreleaseimage (&image);
Cvreleaseimage (&AMP;DST);


Cvdestroywindow ("Smooth Demo");
}
