Goniospectral Imaging of 3D Objects

A multiband imaging system with multi-angle illumination and a processing algorithm for multiband images acquired by the system are presented for extracting goniospectral information of 3D objects. Based on a dichromatic reflection model, multiband images are separated into diffuse and specular components. Then, the model parameters are determined pixelwise and archived. Using these parameters, an image of the 3D object under an arbitrary spectral and spatial distribution of illuminant can be predicted and displayed. A fundamental experiment to confirm the principle of this method is presented.

More about this publication?
  • CIC is the premier annual technical gathering for scientists, technologists, and engineers working in the areas of color science and systems, and their application to color imaging. Participants represent disciplines ranging from psychophysics, optical physics, image processing, color science to graphic arts, systems engineering, and hardware and software development. While a broad mix of professional interests is the hallmark of these conferences, the focus is color. CICs traditionally offer two days of short courses followed by three days of technical sessions that include three keynotes, an evening lecture, a vibrant interactive (poster) papers session, and workshops. An endearing symbol of the meeting is the Cactus Award, given each year to the author(s) of the best interactive paper; there are also Best Paper and Best Student Paper awards.
