Feature Descriptor

A feature descriptor is a mathematical way to describe specific points or patterns within an image, such as edges, corners, or textures. It transforms visual information into a compact numerical representation that captures the unique characteristics of that area. This allows computers to identify, compare, and match the same features across different images, even if they are taken from different angles, lighting, or situations. Feature descriptors are essential for applications like object recognition, image stitching, and 3D reconstruction, enabling machines to interpret and analyze visual data accurately.
