我如何使用JavaCV库将IplImage拆分为HSV通道

IplImage orgImg = cvLoadImage( ... );

IplImage hsv = IplImage.create( orgImg.width(), orgImg.height(), orgImg.depth(), orgImg.nChannels() );
IplImage hue = IplImage.create( orgImg.width(), orgImg.height(), orgImg.depth(), CV_8UC1 );
IplImage sat = IplImage.create( orgImg.width(), orgImg.height(), orgImg.depth(), CV_8UC1 );
IplImage val = IplImage.create( orgImg.width(), orgImg.height(), orgImg.depth(), CV_8UC1 );

cvCvtColor( orgImg, hsv, CV_BGR2HLS );
cvSplit( hsv, hue, sat, val, null );
