ISO/IEC 15938-15:20 19本文档阐述了用于搜索和检索应用的描述符技术，即用于视频中的视觉内容匹配。视觉内容匹配包括大型和小型物体和场景的视图匹配，对部分遮挡以及有利位置、相机参数和照明条件的变化具有鲁棒性。感兴趣的对象包括平面或非平面、刚性或部分刚性、纹理化或部分纹理化的对象，但不包括人和面部的识别。数据库可以很大，例如互联网上可用的广播档案或视频。因此，这样的应用需要与由单帧(静止图像)描述符(例如，与由单帧(静止图像)描述符实现的应用相比，能够与更小的描述符大小和更短的运行时间进行匹配的视频描述符。g.CVDS，ISO/IEC 15938-13）。用于搜索和检索应用的视频分析的紧凑描述符:-实现可互操作对象实例搜索应用的设计；-最小化视频描述符的大小；-确保对象的高匹配性能（在准确性和复杂性方面）；-能够在专业或嵌入式系统上高效实现这些功能。本文件为现有标准套件（如ISO/IEC 15938-13）提供了补充工具。

ISO/IEC 15938-15:2019 This document addresses descriptor technology for search and retrieval applications, i.e. for visual content matching in video. Visual content matching includes matching of views of large and small objects and scenes, with robustness to partial occlusions as well as changes in vantage 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 databases can be large, for example broadcast archives or videos available on the internet. Such applications thus require video descriptors that enable matching with smaller descriptor sizes and shorter runtimes as compared to application enabled by single-frame (still image) descriptors (e.g. CVDS, ISO/IEC 15938-13) in the video domain.
Compact descriptors for video analysis for search and retrieval applications:
- enable design of interoperable object instance search applications;
- minimize the size of video descriptors;
- ensure high matching performances of objects (in terms of accuracy and complexity);
- enable efficient implementation of those functionalities on professional or embedded systems.
This document provides a complementary tool to the suite of existing standards, such as ISO/IEC 15938-13.
