METHOD FOR GENERATING VIDEO WITH VIRTUAL CAMERAWORK USING BI-DIRECTIONAL OBJECT TRACKING BETWEEN KEYFRAMES

摘要

Personal video sharing services such as YouTube have become popular because videos can easily be recorded in high-definition (HD) using a personal camcorder. However, it is difficult to broadcast an HD video via the Internet because of the large amount of data involved. We present a novel method for generating videos with virtual camerawork that is based on object tracking technology. Once a user specifies the positions of the object on keyframes, our method can be used to generate virtual camerawork between two keyframes in a row on the basis of the results of bi-directional tracking. We evaluated our method with subjective experiments and demonstrated its effectiveness.
