Abstract

With the development of multimedia analysis, virtual content insertion has been widely used and studied for the video enrichment and advertising. However, how to less-intrusively insert a virtual content into general videos with an attractive representation is a significant and challenging problem in the field of virtual content insertion. In this paper, we present a novel virtual content insertion system which inserts virtual contents into videos with evolved animations according to predefined behaviors based on the concept of evolutionary biology. The videos are considered as not only carriers of message conveyed by the virtual content but also the environment in which the lifelike virtual contents live. Thus, the inserted virtual content interacts with video contents and triggers the artificial evolution. The evolution process is divided into distinct yet dependent phases, in which the virtual content evolves its appearances and behaviors with the incremental interactions. In this way, the proposed system constructs a visually relevant connection between the inserted virtual content and the source videos to reduce the intrusiveness and increase the acceptability and the attractiveness simultaneously. User studies show that the augmented videos produced by the proposed system improve the audience's viewing experience to the original video content and engage viewers with the entertaining storyline.
