[FIXED] How to make an image red?

Issue

I am working with image processing in Python. How can I transform a scalar image to colored, and then select only the red channel?

I briefly looked into OpenCV and SimpleITK but I cannot manage to find a correct answer.

Solution

I actually did this a couple of weeks ago, the pattern is something along the lines of:

import SimpleITK as sitk

image = sitk.ReadImage(image_path)
rgb = sitk.ScalarToRGB(image)
rgb_array = sito.GetArrayFromImage(rgb)
red_only = [:,:,0]
