Keypoint Descriptors

Keypoint descriptors are unique signatures assigned to specific features or points in images, helping computers recognize and match them across different images. When an image is analyzed, certain points, like corners or edges, are identified as keypoints. Each keypoint is described using a set of numerical values that capture its appearance and context. This allows algorithms to efficiently find and compare similar features in various images, useful in applications like image stitching, object recognition, and 3D reconstruction. Essentially, these descriptors help machines understand and interpret visual information more like humans do.
