opencv classes and libraries. Added all the header files and its libraries to

credential provider for accessing.

Code Like this:

IplImage *frame;
IplImage *showimg;
cvNamedWindow("Input", CV_WINDOW_AUTOSIZE);
camera = cvCaptureFromCAM(0);
cvSetCaptureProperty(camera, CV_CAP_PROP_FRAME_WIDTH, 360);
cvSetCaptureProperty(camera, CV_CAP_PROP_FRAME_HEIGHT, 240);
while(1)
{
frame = cvQueryFrame(camera);
showimg = cvCloneImage(frame);
cvShowImage("Input", showimg);

推荐答案

您不会调用类.您调用函数.您实例化特定类的对象，然后使用它来调用该类中的函数.

You don''t call classes. You call functions. You instantiate objects of a particular class and use it to call functions from that class.
