摘要

本文介绍了一个完全自动化的实时讲师跟踪模块(RTLT)，并将其无缝集成到一个基于物质角的讲座捕捉系统(LCS)中。RTLT模块的主要目的是获取讲师的肖像图像，用于创建集成幻灯片讲师单流，准备在便携式设备中分发和消费，其中显示的内容必须进行优化。该模块使用一组视觉线索实时跟踪任意数量的演示者，并提供帧率元数据，以插入虚拟电影摄影师模块。所谓的Gal跟踪器RTLT模块允许与LCS, Gal cast一起直播，或作为插入Matter horn工作流程的视频制作引擎离线处理。

GaliTracker: Real-Time Lecturer-Tracking for Lecture Capturing

This paper describes a fully automated Real-Time Lecturer-Tracking module (RTLT) and the seamless integration into a Matter horn-based Lecture Capturing System (LCS). The main purpose of the RTLT module is obtaining a lecturer's portrait image for creating an integrated slides lecturer single-stream ready to distribute and consume in portable devices, where displayed contents must be optimized. The module robustly tracks any number of presenters in real-time using a set of visual cues and delivers frame-rate metadata to plug into a Virtual Cinematographer module. The so-called Gal tracker RTLT module allows broadcasting live in conjunction with the LCS, Gal caster, or processing off-line as a video-production engine inserted into the Matter horn workflow.
