cvCreateImage(图片大小,像素位数,通道数)
创建图片，根据输入的图片大小，各个通道像素点的位数，和通道数。像素点宏IPL_DEPTH_8U
cvGetSize(图片)
得到图片的大小信息
cvSmooth(输入图片,输出图片,平滑方式,平滑宽,平滑高)
输出经过平滑处理后的图片，平滑方式宏CV_GAUSSIAN
#include "cv.h"
#include "highgui.h"
void smooth_example(IplImage *image){
cvNamedWindow("hello-in", CV_WINDOW_AUTOSIZE);
cvNamedWindow("hello-out", CV_WINDOW_AUTOSIZE);
cvShowImage("hello-in", image);
IplImage *out = cvCreateImage(cvGetSize(image), IPL_DEPTH_8U, 3);
cvSmooth(image, out, CV_GAUSSIAN, 5, 5);
cvSmooth(out, out, CV_GAUSSIAN, 5, 5);
cvShowImage("hello-out", out);
cvReleaseImage(&out);
cvWaitKey(0);
cvDestroyWindow("hello-in");
cvDestroyWindow("hello-out");
}
int main(int argc, char **argv){
IplImage *img = cvLoadImage(argv[1]);
cvNamedWindow("hello", CV_WINDOW_AUTOSIZE);
cvShowImage("hello", img);
smooth_example(img);
cvReleaseImage(&img);
cvDestroyWindow("hello");
return 0;
}
