T1 - A Framework for Virtual Videography Y1 - 2002 Y2 - June AB - There are a significant number of events that happen on a regular basis that would be worth preserving on video but for which it is impractical to use traditional video production methods. In this paper, we describe one possible way to inexpensively and unobtrusively capture and produce video in a classroom lecture environment. We discuss the importance of cinematic principles in the lecture video domain and describe guidelines that should be followed when capturing a lecture. We continue by surveying the tools provided by computer vision and computer graphics that allow us to determine syntactic information about images. Finally, we describe a way to combine these tools to create a framework for a Virtual Videography system, one that can automatically generate production quality video. This framework is based on the creation of region objects, a semantically related region of video, despite the fact that we can reliably only gather syntactic information.

T1 - Chalkboard and Marker Regions Y1 - 2005 Y2 - March AB - When recording a classroom lecture, it is useful to capture the writing on the board for processing by applications. To provide more useful information for applications, we group together strokes based on the meaning of the writing. However, it is currently not possible to automatically obtain this meaning, or general semantic information automatically. Instead we rely on the structure of writing to approximate regions of the board, where each region represents a single thought or idea. These regions provide an abstraction of the board that can be used in several applications, such as a note taker, a lecture indexing program, an automatic video editor, and a program for creating multimedia presentations. N1 - This paper formely describes regions and the region concept.

Users of web-based classes and conferences would like to have access to the projector tools. The bandwidth required to transmit these projections is too large to be useful. This paper proposes a framework for processing images displayed by overhead and computer projectors during presentations. In this way, the projectors can be easily rebroadcast over the internet without loss of quality due to compression. This process requires determining the areas of text, binarizing those areas, and performing Optical Character Recognition on the final image. Several examples are shown, including both successful and unsuccessful data sets. A discussion is also included which explains all of the results.

Additionally, lecture rooms may be outfitted with several cameras for this purpose. However, recording the interactions alone does not create effective video. In this paper we present a method for not only recording, but also editing in real-time, lectures. Unlike previous work, the system is highly portable, allowing quick set-up in various types of lecture rooms. This portability is achieved by using the abstraction of virtual cameramen and physical cameras, and a scriptable interface to the editing rules.
