Converting Numpy Array to OpenCV Array

Question

I\'m trying to convert a 2D Numpy array, representing a black-and-white image, into a 3-channel OpenCV array (i.e. an RGB image).

Based on code samples and the docs

Answer 1

The simplest solution would be to use Pillow lib:

from PIL import Image

image = Image.fromarray(.astype(np.uint8))

And you can use it as an image.
