This part of the MPEG-7 standard provides the reference software, specifies the conformance testing, and gives usage guidelines for ISO/IEC 15938-13: Compact descriptors for visual search (CDVS). CDVS 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. This document is a Committee Draft (CD) text for ballot consideration and comment for ISO/IEC 15938-14: Reference software, conformance and usage guidelines for compact descriptors for visual search.
