Towards Virtual Videography

摘要

Videographers have developed an art of conveying events in video. Through choices made in cinematography, editing, and post-procesisng, effective video rpesentations can be created from events recorded with little or no intrusion. In this paper, we explore systems that bring videography to situations where cost or time issues preclude application of the art. Our goal is to develop virtual videography, that is, systems that can help automate the process of creat-ing an effective video pressentation from given footage. In this paper, we discuss how virtual videography systems can be constructure by combinig image-based rendering to synthetically generate shots with image understanding to help choose what should be shown to the viewer. To this, visual choose that should be shown to the viewer. To this, visual effects can be added to enhance the presentation, lessening the degradation caused by the medium.
