1. Introduction

The computer scientists have, since 1990s, made remarkable progress in developing algorithmic codes for autonomous agents. Such behaviors have been instrumental in navigation in digital environments using strategies such as wandering, seeking, arriving, fleeing, evading or even avoiding an obstacle. On the other hand, match moving has become a major standard procedure for visual effects for all situations where CG and action materials get combined. This allows real and virtual scenes that are composited together to enable them appear seamlessly as though from the same perspective (Hornung, 2010).

The match moving technique enables insertion of computer graphics to a live-action footage with scale, correct position, motion and orientation relative to the photographed objects within the shot (Hirabayashi, 2002). Match moving have been primarily used in tracking camera movements through a shot to enable an identical virtual camera to be moved in order to be reproduced using the 3D animation program. The compositing of animated elements into original live action enhances a perfect appearance in a marched perspective; hence appear as seamless. The benefits of the match moving are abundant providing comprehensive expressive attributes to the motion pictures (Hoshino, Masanobu, & Hirofumi, 2001).

Realistic character motion is critical in media production like computer games and films. Use of lifelike characters produces special effects which facilitate the immersive experiences. Nevertheless, creation of realistic motions can be challenging. Matchmove is a mystery to several people (Reynolds, 2007). This is because noticing a match move can be quite challenging. Match move takes the information from the real life set where a film is shot and recreate the camera while ensuring the focal length, tilt, height, motion and position relative to the subject within the CG environment. Thereafter, after the creation of CG world, the film is rendered or photographed using the virtual CG twin of real-life camera (Sijll, 2005).

In this way, CG elements created within the virtual world will possess the same depth, perspective, same relationship and the same depth to the moving camera similar to the live characters. This allows seamless integration into the live plate ready for the final shot (Wilk, 2014).

 After creation and approval of 3D camera solutions, there may appear other elements to be matched. The interaction of the of full CG character with a live character requires addition of a virtual scene and the movements should be animated in order to match the movements of a live actor (Menache, 2000). The CG effects can also be applied to real life actor covered with real life goo. In other cases, arms, heads or other body parts can be replaced with the CG elements in order to seamlessly blend with live action plate (Cantrell & Natalie, 2012). The animated CG puppets are required in casting the reflections and shadows on the CG elements added to the scene (Park & Bum-Jong, 2008).
