Abstract: This study presents a novel approach to integrating virtual objects into a video of real objects with illumination consistency to enrich a video environment with virtual information. In order to achieve consistent composite results and make virtual and real objects appear as it coexists in the same environment, three key issues in achieving mixed reality need to be processed are geometry, illumination and time. This study focuses on the second issue and proposes several techniques for interactively projecting shadows of the "real video onto the virtual objects. The proposed system can be dividing into three phase: moving object detection phase, tracking phase and mixing phase. Moving object detection phase, include background subtraction and segmentation technique. Tracking phase include features extracting such as edge, area and center points to each existing object and then tracking these objects. Thus, the object-tracking technique uses center points of the certain object from each frame of a movie file for extracting trajectory. Mixing phase, include merge virtual objects back to the real video scene and illumination consistency to match shade and shadow in both videos to achieve a natural merge.
