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, WebJan 4, 2024 · Image registration is a digital image processing technique that helps us align different images of the same scene. For instance, one may click the picture of a book from various angles. Below are a few instances that show the diversity of camera angles. Now, we may want to “align” a particular image to the same angle as a reference image.
