Reading images using opencv-python

In this post, I introduce a way for reading images using opencv-python . Suppose that the Python project will be managed by Pipenv (see my previous post).

Installation

You can install opencv-python using pip:

pipenv install opencv-python

If you try to build official software, you should specify the version of package. The version can be found on PyPI. The latest version of opencv-python is 4.5.1.48 at 2021/01/05.

You can specify the version like this:

pipenv install opencv-python~=4.5.1.48

Reading image by cv2.imread

You can read images by the function cv2.imread like this:

import cv2

image = cv2.imread('/path/to/imagefile')

Change /path/to/imagefile to the path of your image. After reading image, the variable image above is numpy.ndarray . If you understand how to manipulate numpy.ndarray , you can easily conduct image processing.
