A LCD cube transporting high dynamic range light environments
  In the MR world, it needs to overlay virtual objects ontoreal scene with harmonizing the photometric consistency.We developed a new illumination device “LCD cube” forkeeping photometric consistency. In the demonstration,we plan to present the method to display high dynamicrange light environments by “LCD cube” for Image-Based Lighting. In addition, we performed a lightreproduction in real-time.

A Virtual Color Reconstruction System for Real Heritage with Light Projection

  • # Takenobu Yoshida, Chinatsu Horii, Kosuke Sato, A Virtual Color Reconstruction System for Real Heritage With Light Projection, 9th International Conference on Virtual Systems and MultiMedia (VSMM2003), pp. 825-831 (2003)

A Virtual Color Reconstruction System for Real Heritage with Light Projection
  This paper presents a new Mixed Reality system for controlling the realobject’s color appearance with a simple projection method. This system illuminates thereal object with the color light of four test patterns in advance and then, it estimates whatcolor should be applied for color correction. This approach reconstructs the object’s colorinto the other one without defusing the painterly brushwork. It is possible to visualize therestoration for real color-deteriorated heritage arts and to provide a new fun for amateurpainter as like a famous one. In this paper, we explain the experimental result forchanging the color appearance of real heritages, painting and bronze bell-shaped vessel.
