How to Access Pixel Data in Image using Python OpenCV

To Access Pixel Data in Image using Python OpenCV, use array shape and size property to get the width, height, channel, and pixels.

OpenCV-Python is the Python library designed to solve computer vision problems. We can read the Image using the  imread() function, write or save the Image using the  imwrite() function, display the image in the image window using the  imshow() method.

How to Access Pixel Data in Image

To access pixel data in Image, use  numpy and opencv-python library. Import numpy and cv2(opencv-python) module inside your Python program file. Then read the image file using the imread() function. The imread() Method takes two parameters.

  1. Image path
  2. Channel(If 1 then black and white and if 2 then color)

Let’s print the Image.

## app.py

import numpy as np
import cv2

img = cv2.imread('forest.jpg', 1)

print(img)

Create a Virtual Pen and Eraser with Python OpenCV - Genial Code

Learn Free how to create a virtual pen and eraser with python and OpenCV with source code and complete guide. This entire application is built fundamentally on contour detection. It can be thought of as something like closed color curves on compromises that have the same color or intensity, it's like a blob. In this project we use color masking to get the binary mask of our target color pen, then we use the counter detection to find the location of this pen and the contour to find it.
