Orb homography

Webestimating the homography transform between two frames that capture the same scene, they can be overly expensive for real-time video stabilization [8]. For this reason, we opted to use ORB, a computationally-efficient alternative to SIFT and SURF [8]. ORB, which stands for Oriented FAST and rotated BRIEF, WebOrb weavers are a family of harmless spiders (Araneidae) that spin large orb-shaped webs to catch their prey. They come in a large number of sizes, colors and shapes and are …
