Virtual Camera Tools for an Image2Video Application

This paper proposes a set of virtual camera tools developed as a part of an image to video system, oriented to the adaptation of large images to be viewed on small displays without a significant loss of information. This transmoding system automates the process of scrolling and zooming through an image with a minimal user interaction by simulating a virtual camera movement through the picture. The process is automatic and the user interaction will be limited to establish some preferences on the video generation. The focus of this article is the presentation of the algorithms designed to obtain smooth, user-customizable camera movements.
