What is the Truth: A Survey of Video Compositing Techniques

By Mahmoud Afifi Khaled F. Hussain

DOI:, Pub. Date: 8 Jul. 2015

The compositing of videos is considered one of the most important steps on the post-production process. The compositing process combines several videos that may be recorded at different times or locations into a final one. Computer generated footages and visual effects are combined with real footages using video compositing techniques. High reality shots of many movies were introduced to the audience who cannot discover that those shots are not real. Many techniques are used for achieving high realistic results of video compositing. In this paper, a survey of video compositing techniques, a comparison among compositing techniques, and many examples for video compositing using existing techniques are presented.

Cut off Your Arm: A Medium-Cost System for Integrating a 3D Object with a Real Actor

By Mahmoud Afifi Mostafa Korashy Ebram K. William Ali H. Ahmed Khaled F. Hussain

DOI:, Pub. Date: 8 Oct. 2014

In the film industry, many tricks have been employed using the integration of a 3D object with a real actor. Usually, attaching a 3D object with a real actor is a costly process because of the usage of an expensive motion capture system. This paper presents a system using a medium-cost motion capture system and a chroma-keying technique for generating a video footage of an actor with an integrated 3D object (e.g. amputated arm). The result of the proposed system shows the attaching process of different 3D objects with a real actor who is combined with a new background scene in the same viewpoint.
