Example of Basic Image Processing in OpenCV

import cv2
import numpy as np

# Load an image
image = cv2.imread('path/to/image.jpg')

# Convert to grayscale
gray_image = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)

# Apply GaussianBlur
blurred_image = cv2.GaussianBlur(gray_image, (5, 5), 0)

# Edge detection using Canny
edges = cv2.Canny(blurred_image, 100, 200)

# Display the result
cv2.imshow('Edges', edges)
cv2.waitKey(0)
cv2.destroyAllWindows()
