This document describes the Compact Descriptors for Visual Search (CDVS) Test Model (TM) 13.0 (CDVS1) (CDVS2). In particular, this document looks at the TM architecture, the operation of the informative component technologies (descriptor matching and retrieval) of the TM, and the offline or training procedures for both the normative (descriptor extraction) and the informative (descriptor matching and retrieval) component technologies of the TM.

Published in meeting:

This document is a working draft toward development of reference software and conformance testing specifications for Compact Descriptors for Visual Search (CDVS).

Standard:
Published in meeting:

This part of ISO/IEC 15938 contains simulation software for tools defined in parts 1, 2, 3, 4 and 5 of ISO/IEC 15938. This software has been derived from the verification models used in the process of developing the International Standard.

This document is a (non-final draft) of the CDVS conformance test dataset and conditions. The conformance test dataset comprises a set of 1000 images. Reference bitstreams for the conformance test dataset are also provided. For each image cdvsxxx.jpg in the conformance dataset, six reference bitstreams are provided corresponding to the six descriptor lengths specified in the CDVS standard.

This document is a working draft of a specification for CDVS (compact descriptors for visual search) reference software.

The CDVS reference software is entirely written in C and C++. On Windows, it has been compiled and tested on Windows 7 Enterprise 64-bit using Visual C++ 2010 (64 bit). On Linux, it has been compiled and tested on Ubuntu 14.04 LTS (64-bit).
