Towards a realistic marker-based augmented reality scene: issues and prospective aspect

This paper describes the main problems in realistic Augmented Reality scenes. In order to view the real world with additional computer-generated information in a seamless and realistic integration, there are several research challenges that can be identifiedsome related to camera tracking, system design, user interaction, and rendering. The focus on each of these aspects was thoroughly explored by several methods and techniques. This study is considered to be an exploration for an Augmented Reality rendering technique. This technique focuses on increasing the realism in the AR scene. Thus, in order to realize the AR scene in a more realistic way, there are four main issueslight source detection, well-designed virtual objects that can have true reflex of the real environment, then integration of a real-time accurate soft shadow
