You can use the following code:

IplImage* src0 = cvLoadImage(strPath, CV_LOAD_IMAGE_GRAYSCALE);
IplImage* src = cvCreateImage(cvGetSize(src0), IPL_DEPTH_32F, 1);
cvConvert(src0, src);
IplImage* dst = cvCreateImage(cvGetSize(src0), IPL_DEPTH_32F, 1);

cvDCT(src, dst, 0);
//cvDCT (dst, src, 1);
//cvConvert(src, src0);
cvShowImage("Source", src0);

The manual explains both the parameters and the inner workings of the function.
