Overview of compact descriptors for visual
search
This part of the MPEG-7 standard specifies an image description
tool designed to enable efficient and interoperable visual search
applications, allowing visual content matching in images. Visual
content matching includes matching of views of objects, landmarks,
and printed documents, while being robust to partial occlusions as
well as changes in viewpoint, camera parameters, and lighting
conditions.
