DESIGN AND REALIZATION OF MAP DIGITIZATION SYSTEM ON MICRO-COMPUTER BASED MAP GRAPHIC WORKSTATION

A Utility Map Transformation System Based on Map Understanding

In recent years some electric power companies or gas suppliers have begun to use computerized utility map management systems. And there is a demand to share their utility data with each other. But that is difficult because their topographic maps, which give the base of equipment location, are different. So we developed an automatic transformation method of utility data, which transforms utility...

Computer Aided Color Appearance Design using Environment Map Based Lighting

A BRDF approximation is developed that is suitable for interactive color appearance design in direct lighting provided by environment maps. The BRDFs are approximated as a linear combination of cosine lobes with a fixed set of specular exponents. A nonlinear optimization routine is used to fit the cosine lobes to BRDFs appropriate for a specific color appearance design application: automotive p...
