Video composition is an indispensable technique in the production of many types of videos; nevertheless, it remains challenging problem if the source video is normally captured without a blue or green screen, especially when the object to be pasted between videos does not have a clear boundary (e.g. water, gas, and fire). We will call such a region a secondary foreground, and we propose a simple composition method in which foreground, background, and secondary foreground weights are determined using a geodesic distance tramsform [Criminisi et al. 2010]. This method will run in real time, but is nevertheless able to produce convincing results with difficult secondary foregrounds.
