An Interactive Digital Fishtank Based on Live Video Images
This paper describes an interactive manipulation technique for objects extracted from video images by an efficient algorithm in order to produce multimedia contents. An object contained in a video image must be able to be extracted at a reasonable speed and a moving object able to be tracked with sufficient accuracy. Moreover, real object interactions that meet such criteria must be established using techniques for manipulating objects in virtual worlds. The proposed technique has potential to generate novel multimedia contents without using shape modeling. An interactive digital fishtank is described as one example application of the proposed technique. In this application, the user is able to obtain various video sequences of fishtanks from the original video sequence.
