Description
Summary:Virtual camera controls (VCC) for digital video enable the viewers to visualize interesting objects from their perspective. VCC also allow us to play the video from different angles. In this sense, VCC do not only support visualization and browsing capabilities but also support playback from different angles. VCC management requires accurate global motion estimation and accurate sprite generation. After motion parameters are detected and the precise sprite is generated, virtual camera controls are used to manipulate the sprite and the original frames to allow interactive spatial browsing and playback that enables panning, tilting, and zooming
