How do I make an image 8-bit grayscale?
To convert an image from RGB to 8-bit grayscale is a form of downsampling in which 24-bit information must be compressed into an 8-bit range. The simplest method to achieve this is a direct conversion which averages the Red, Green, and Blue values for each pixel.

How do I binarize an RGB image?
imbinarize interprets an RGB image as a volumetric grayscale image and does not binarize each channel separately. To produce a binary image from an RGB image, first convert the image to a grayscale image using rgb2gray. Method used to binarize image, specified as one of the following values.
How to convert an RGB image to binary type image?
To convert an RGB image into a binary type image, we need OpenCV. So first of all, if we don’t have OpenCV installed, then we can install it via pip:
How to binarize an image into black and white with a threshold?
This article describes how to binarize an image into black and white with a threshold. There are two ways: one is to use OpenCV function cv2.threshold (), and the other is to process ndarray with a basic operation of NumPy. OpenCV is not necessary in the latter case.
