Keypoint Descriptor

A keypoint descriptor is a tool used in image processing and computer vision to identify and describe features in images. When an image is analyzed, specific points with unique characteristics, called keypoints, are detected. The descriptor captures information about the appearance or texture around each keypoint, creating a signature for it. This allows software to recognize and match similar features across different images, which is useful for tasks like object recognition, image stitching, and tracking movements in videos. Essentially, it's a way for computers to understand and compare visual information effectively.
