How can I use OpenCV for image processing?

OpenCV is a powerful library for image processing. You can start by installing it using pip: pip install opencv-python. What specific tasks are you interested in?

I want to perform edge detection on images.

For edge detection, you can use the Canny edge detection method. Here's a simple example:

import cv2

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

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

# Apply Canny edge detection
edges = cv2.Canny(gray, 100, 200)

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

What parameters should I adjust for better results?

You can adjust the thresholds in the cv2.Canny() function. The first parameter is the lower threshold, and the second is the upper threshold. Experimenting with these values can help you achieve better edge detection results.
