Conversion between opencv and javacv

I'm thinning an binary image. I found code done by using opencv. Here is the code.

eroded = cv2.erode(img,element)
temp = cv2.dilate(eroded,element)
temp = cv2.subtract(img,temp)
skel = cv2.bitwise_or(skel,temp)
img = eroded.copy()

I'm trying to convert this code to java via javacv. Both erosion and dilation completed successfully as follows.

skelImg=cvCloneImage(otsuImg);
cvErode(otsuImg, skelImg, null, 1);
cvDilate(skelImg, skelImg, null, 1);

But I couldn't find javacv code for cv2.subtract(IplImage,IplImage). Can someone help me out with this?

Rather than use the javacv wrapper to OpenCV's deprecated API, consider using the following methods from OpenCV's official Java API:

There is one subtract function in Core. See this for better understanding
