Question

When I try to change the Image Channel of Interest (setImageCOI), Python gives me this error:

im = cv2.imread('image.jpg')
cv2.setImageCOI(im, 1)
AttributeError: 'module' object has no attribute 'setImageCOI'

Do I need to specially install the modules that allow for operations on arrays?

Answer 1

That method is implemented in the cv module under SetImageCOI (notice the capital S):

import cv
cv.SetImageCOI(im, 1)
