If Canny is the Ferrari of edge detection, Sobel and Laplacian are the dependable Toyotas – easier however efficient.
Methodology 2: Sobel – Detecting Horizontal & Vertical Edges
# Apply Sobel operator
sobel_x = cv2.Sobel(picture, cv2.CV_64F, 1, 0, ksize=5) # Detects vertical edges
sobel_y = cv2.Sobel(picture, cv2.CV_64F, 0, 1, ksize=5) # Detects horizontal edgescv2.imshow("Sobel X", sobel_x)
cv2.imshow("Sobel Y", sobel_y)
cv2.waitKey(0)
cv2.destroyAllWindows()
🔴What’s Taking place?
Sobel X finds vertical edges
Sobel Y finds horizontal edges
Nice for detecting directional particulars!
✅ Why Use Sobel?
- Quicker than Canny ⏩
- Helpful to detect textures & patterns
🍓Methodology 3: Laplacian – The All-Course Edge Detector
# Apply Laplacian operator
laplacian = cv2.Laplacian(picture, cv2.CV_64F)cv2.imshow("Laplacian", laplacian)
cv2.waitKey(0)
cv2.destroyAllWindows()
🔴What’s Taking place?
In contrast to Sobel, it detects edges in all instructions.
Finest for highlighting fantastic particulars! ????
✅ Why Use Laplacian?
- Tremendous easy & environment friendly
- Works good for noisy pictures!
