Video Collage: A Novel Presentation of Video Sequence
This paper presents an automatic procedure for constructing a compact synthesized collage from a video sequence. The synthesized image called video collage, is a kind of static video summary - to select most representative images from video, to extract salient regions of interest (ROI) from these images and resize them according to their saliency, and to seamlessly arrange ROI on a given canvas with the temporal structure of video content preserved. We formulate the generation of video collage as an energy minimization problem in which each of above desirability is represented by an energy term. Unlike most existing video presentation schemes, video collage is more compact and visually appealing. We have applied video collage on several home videos and report superior performance in a user study compared with key existing approaches to video presentation.
