body: <p>I want to display original image left side and grayscale image on right side. Below is my code, I create grayscale image and create window, but I couldn't put grayscale image to right side. How can I do this? </p>
  
  <pre><code>import cv
  import time
  from PIL import Image
  import sys
  
  filePath = raw_input("file path: ")
  filename = filePath
  
  img = cv.LoadImage(filename)
  imgGrayScale = cv.LoadImage(filename, cv.CV_LOAD_IMAGE_GRAYSCALE) # create grayscale image
  
  imgW = img.width
  imgH = img.height
  
  cv.NamedWindow("title", cv.CV_WINDOW_AUTOSIZE)
  cv.ShowImage("title", img )
  cv.ResizeWindow("title", imgW * 2, imgH)
  
  cv.WaitKey()
  </code></pre>
