Outline of Final Research Achievements

(1) We have developed several methods for separating diffuse and specular reflections. One checks the fitness of the intensity change to Lambert law, and the other uses the intensity response to the high spatial frequency lighting patterns. (2) A fast measurement method of anisotropic reflection distribution function using small number of spatial frequency illumination patterns has developed. (3) We have developed projection-mapping based HDR image display on a real 3D object using calibrated light projection onto the colored object generated by the color 3D printer. (4) A selection method of optimal projector in a multi-projector environment to show the optimal image on the object has developed. (5) Extension of depth of field of a projector based on the focus sweep method has developed.
