Mar 01, 2020 · This post is the first of several image processing tutorials that are to follow. We take a closer look at the pixels that make up an image, learn how to install OpenCV on the Raspberry Pi (with a Raspberry Pi Camera ) and we also write test scripts to capture an image and also carry out colour separation using OpenCV.

It is a non-linear operation that converts a gray-scale image into a binary image where the two levels are assigned to pixels that are below or above the specified threshold value. In other words, if pixel value is greater than a threshold value, it is assigned one value (may be white), else it is assigned another value (may be black). In OpenCV, we use cv2.threshold () function:
