I used python and openCV library. I would like to count white pixels from bottom of binary image.

This is my idea :-

for j in range(240, 0, -1):
      for i in range(140, 320, +1):
          if _____ :   #white pixels found at the bottom.Don't know what should I fill in that space.
                   count_white : cv2.countNonZero(img)   # is this command correct??
                   print count_white

Do I need 'for loop' to count pixels from bottom? How to count the pixels?

I really need your help. Thanks.

okay. if I do a watershed, how to write the 'for loop' coding which start from the bottom. I have no idea..

No. I'm referring to this link http://www.roborealm.com/tutorial/Obs... . I got the edge detection image but I don't know how to coding the side fill from bottom.

How to write coding 'for loop' function to read pixels from bottom to top. Also how to do the side fill from bottom to the top of binary image after edge detection.

This is the image after edge detection :

I'm using python 2.7.3 and opencv 2.4.9
