public class main {
public static void main(String[] args) {
    // TODO Auto-generated method stub

    IplImage img = cvLoadImage("images.png");
    IplImage hsvimg = cvCreateImage(cvGetSize(img),IPL_DEPTH_8U,3);
    IplImage grayimg = cvCreateImage(cvGetSize(img),IPL_DEPTH_8U,1);

    cvCvtColor(img,hsvimg,CV_BGR2HSV);
    cvCvtColor(img,grayimg,CV_BGR2GRAY);

    cvShowImage("Original", img);
    cvShowImage("HSV", hsvimg);
    cvShowImage("GRAY", grayimg);
    cvWaitKey();

    cvSaveImage("Original.jpg",img);

}

}

我的＆＃34; IPL_DEPTH_8U，CV_BGR2HSV＆＃34;我没有工作，我从YOUTUBE这个教程中获取了这段代码，我尝试了很多次，但这不起作用请帮助我。
