Which one is better for real-time applications?
ORB is generally better for real-time applications due to its speed and lower computational cost compared to SIFT.
Are there any scenarios where SIFT would be preferred over ORB?
Yes, SIFT is preferred in scenarios where accuracy and robustness to scale and rotation are critical, such as in complex image matching.
Can you give examples of applications for both SIFT and ORB?
SIFT is often used in object recognition and 3D reconstruction, while ORB is commonly used in mobile applications and augmented reality.
