A way cutting an image in OpenCV

But how I can do it on OpenCV in Python? This is what I tried:

    image = cv.imread('back.png', cv.CV_LOAD_IMAGE_GRAYSCALE)
    (thresh, im_cd) = cv.threshold(image, 87, 34, cv.THRESH_OTSU)
    image = cv.getRectSubPix(im_cd, (120, 60 ), (10, 10))
    cv.imshow('Img', image)
    cv.waitKey(0)

But it doesn't work. Help me. It is urgent problem

I had this problem 10 days ago. This is solution I think.

import cv2
img = cv2.imread("lenna.png")
crop_img = img[y:y h, x:x w]
cv2.imshow("cropped", crop_img)
cv2.waitKey(0)

Also I wanna know about C Solution using OpenCV. Because if python not, I will do using C .
