Chromatic Aberration, Linear Models, and Matching Color Images

In an earlier paper, we modeled the axial chromatic aberration of the human eye with an optical transfer function (OTF). The OTF quantifies the interaction between wavelength and spatial pattern in retinal image formation, and therefore has important consequences for color perception and image matching. However, using the OTF for practical calculations can be quite cumbersome. Here, we show how using finite dimensional linear models for surface and illuminant spectral functions greatly simplifies these calculations in certain cases. In our earlier wow, we applied our model to the problem of matching color images on missive displays; we show here how this application is a special case of this use of linear models.

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.
