#### Smoothing image in OpenCV

This is a simple program which is Loading and then smoothing an image before it is displayed on the screen.

```
#include "highgui.h"
#include "cv.h"
int main(int argc, char** argv) {

cvNamedWindow("Input", 9);
cvShowImage("Input", in_img);

IplImage* out_img = cvCreateImage(cvGetSize(in_img), IPL_DEPTH_8U, 3);
cvSmooth(in_img, out_img, CV_GAUSSIAN, 11, 11); // should use 2 odd numbers

cvNamedWindow("Output", 9);
cvShowImage("Output", out_img);
cvWaitKey(0);

cvReleaseImage(&in_img);
cvReleaseImage(&out_img);

cvDestroyWindow("Input");
cvDestroyWindow("Output");

return 0;
