title: How to crop the images inside the bounding box from findContours
body: <p>I plotted bounding box using the cv2.rectangle method by finding Contours. Now i want to crop each bounding box.</p>
  
  <p>I tried slicing method to crop the images which didn't provide me the desired result. It cropped the regions that do not have any bounding box in it.</p>
  
  <pre><code>#Plotting rectangular box
  ret,thresh = cv2.threshold(dilation, 127,255,0)
  image, contours,hierarchy = cv2.findContours(thresh, cv2.RETR_TREE,cv2.CHAIN_APPROX_NONE )
  
  for c in contours:
      rect = cv2.boundingRect(c)
      if rect[2] &lt; 100 or rect[3] &lt; 100 : continue
      print (cv2.contourArea(c))
      x,y,w,h = rect
  
      crop_img = img[x:x+w, y:y+h] #Cropping
      cv2.imwrite("Cropped/"+str(enumerate(c))+".jpg", crop_img)
  
      cv2.rectangle(im_new,(x,y),(x+w,y+h),(0,255,0),2)
  
  cv2.imwrite('sample_res_inner.jpg',im_new)
  cv2.waitKey()  
  cv2.destroyAllWindows()
  </code></pre>
  
  <p>What changes can I make to the code to yield the desired result?</p>
