OpenCV Python: Normalize image
<p>I'm new to OpenCV. I want to do some preprocessing related to normalization. I want to normalize my image to a certain size. The result of the following code gives me a black image. Can someone point me to what exactly am I doing wrong? The image I am inputting is a black/white image</p>

<pre><code>import cv2 as cv
import numpy as np

img = cv.imread(path)
normalizedImg = np.zeros((800, 800))
cv.normalize(img,  normalizedImg, 0, 255, cv.NORM_MINMAX)
cv.imshow('dst_rt', self.normalizedImg)
cv.waitKey(0)
cv.destroyAllWindows()
</code></pre>
