Hideki Imai Professional Highlights 1988 to 1989 Research Trainee, Department of Physics, Instituto Tecnol¢gico de Aeronautica, S_o JosÇ dos Campos, SP, Brazil 1990 Engineering apprenticeship (Co-op), Tecnasa SA, S_o JosÇ dos Campos, SP, Brazil 1996 to 1997 Teaching Assistant, Department of Engineering, Chiba University, Japan 1997 to 2000 Post-doctoral fellow, Munsell Color Science Laboratory, Rochester Institute of Technology, Rochester, NY, USA 2000 to 2003 - Senior Color Scientist, Munsell Color Science Laboratory, Rochester Institute of Technology, Rochester, NY, USA 2003 to present - Senior Color Scientist, Pixim Inc. I joined the Munsell Color Science Laboratory in September 1997 as a post-doctoral fellow. My research focused in a project involving multi-spectral image capture that is a natural extension of a part of my doctoral dissertation about facial pattern image reproduction based on colorimetry and either linear modeling or iterative non-linear techniques. The main challenge in my research was overcoming the limitations of low spatial resolution of current multi-spectral image acquisition by combining low-resolution multi-spectral images with high-resolution silver halide images. After studying the bibliographical references related to my research, defining the experimental system and methodology I started doing simulations to improve the spectral reconstruction based on a colorimetric trichromatic IBM digital camera combined with a set of absorption filters. I was a staff member as color scientist fromAugust 2000 to September 2003. In 2003 I moved to California and currently work for Pixim, Inc. at Mountain View, CA. Publications 54.
