What is OpenCV in Python? | Computer Vision Explained for Beginners
What is OpenCV in Python? 🚀
In this beginner-friendly video, you'll learn what OpenCV is, how Computer Vision works, and how Python can be used to process and analyze images and videos.
OpenCV (Open Source Computer Vision Library) is one of the most popular libraries for Computer Vision. It allows developers to work with images, videos, webcams, object detection, face detection, and many other visual applications.
💻 INSTALL OPENCV
pip install opencv-python
🔹 VERIFY INSTALLATION
import cv2
print(cv2.__version__)
🔹 BASIC OPENCV EXAMPLE
import cv2
image = cv2.imread("image.jpg")
gray_image = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)
resized_image = cv2.resize(gray_image, (500, 300))
cv2.imwrite("processed_image.jpg", resized_image)
🧠 BEGINNER CHALLENGE
Try creating your own Python program that:
✅ Opens an image
✅ Converts it to grayscale
✅ Resizes the image
✅ Saves the processed image
