What are descriptors in image processing?
In computer vision, visual descriptors or image descriptors are descriptions of the visual features of the contents in images, videos, or algorithms or applications that produce such descriptions. They describe elementary characteristics such as the shape, the color, the texture or the motion, among others.
What is a local descriptor computer vision?
A local descriptor describes a patch within an image. Using multiple local descriptors to match an image is more resilient than relying on one sole descriptor. The local descriptors SIFT, SURF, LBP, BRISK, MSER, and FREAK are a few examples.
