This document provides Working Draft 2 of Compact Descriptors for Video Analysis.
~~The purpose of this document is to provide descriptions of six core experiments on MPEG Compact Descriptors for Video Analysis (CDVA). The previous six CEs are being continued.
The results of experiments will be discussed on the reflector before the 121st MPEG meeting.
The report of each CE should include; (1) a comparison between the tested solutions, (2) recommendation to the AhG based on the results of the CE.
CDVA defines video descriptors for search and retrieval applications, specifically for visual content matching in video. Visual content matching includes matching of views of large and small objects and scenes, that is robust to partial occlusions as well as changes in view point, camera parameters, and lighting conditions. The objects of interest comprise planar or non-planar, rigid or partially rigid, textured or partially textured objects, but exclude the identification of people and faces.

The current media and entertainment domain is characterized by increasing volumes of content, large number of delivery channels and an ever-growing need for the relevant content to be accessed on demand or published quickly. This is very difficult without appropriate tools to manage content items, including search for object instances in video, categorisation of scenes and content grouping. Thus, the ability to generate and exchange compact and standardized descriptors in an interoperable and efficient way is considered a key enabler in this domain.
The purpose of this document is to provide descriptions of six core experiments on MPEG Compact Descriptors for Video Analysis (CDVA). The previous three CEs have been reviewed, and based on the responses received and the open issues they pose, one additional CE on matching and retrieval has been added, and the CEs related to deep-learning based descriptors have been split. The description of all CEs has been improved, adding more details on the experiments and expected results.
The results of experiments will be discussed on the reflector before the 119th MPEG meeting.

The purpose of this document is to provide descriptions of three core experiments on MPEG Compact Descriptors for Video Analysis (CDVA) based on the proposals submitted at 114th MPEG meeting and the submission to the 115th and 116th meeting. In addition to the CEs defined in the earlier version of this document, the submissions to the 116th proposed the use of deep-learning-based descriptors and related experiments, which have been added as CE4. CE2 on trajectory based encoding has been discontinued.

At its 112th meeting, MPEG issued a call for proposals for Compact Descriptors for Video Analysis (CDVA) - Search and Retrieval. In response to the CfP, three full proposals and one partial proposal (addressing trajectory coding) were received. At the 114th meeting, these proposals were evaluated and analyzed. This document provides a summary of the full proposals received and provides the preliminary evaluation results obtained at the meeting.
This document describes data requirements for CDVS.
Current industry systems implement the "Compress then Analyse (CtA)" paradigm, where a video is compressed using traditional video encoding methods, for further analysis.
Guided by the requests and requirements from different industries, MPEG recently started preparations to develop tools for video processing and analysis. They will address the challenge to reverse CtA into the "Analyse then Compress (AtC) paradigm to reduce the data amount for their transmission or storage and to achieve interoperability of implementations, applications and databases.
