Σύνοψη	ORB (Oriented FAST and Rotated BRIEF) combines the FAST corner detector with the BRIEF binary descriptor to create a fast, rotation-invariant feature detector and descriptor. Introduced by Rublee et al. in 2011, ORB is designed as a free, efficient alternative to patented methods like SIFT and SURF, making it ideal for real-time and resource-constrained applications.	The Harris corner detector, introduced by Chris Harris and Mike Stephens in 1988, is a foundational method for identifying corners and interest points in digital images. Harris corners are points where two edges meet at a significant angle, making them stable and repeatable features for image analysis, matching, and 3D reconstruction.
