What are binary descriptors?

Binary image descriptors encode patch appearance using a compact binary string. The hamming distance in this space is designed to follow a desired image similarity measure typically sought to be invariant to scene illumination and viewpoint changes.

What are descriptors in feature vectors?

The feature descriptor describes an interest point and encodes the description in the form of a multidimensional feature vector in the vector space.

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 brief descriptor?

BRIEF (Binary Robust Independent Elementary Features) is an efficient feature point descriptor. It is highly discriminative even when using relatively few bits and is computed using simple intensity difference tests.
