MTF (Modulation Transfer Function) is useful to characterize the response of a linear imaging system, namely MTFs of the imaging systems and human eye determine the overall sharpness quality. Therefore various merits used MTF have been proposed and applied for evaluation of image quality. However, almost merit used MTF is not considered anisotropy properties of imaging system and human eye response.

In this paper, dependence of the directivity of contrast sensitivity of human eye in various luminance, RGB color space and opponent color space is measured and analyzed. On the basis of those measured contrast sensitivities, two-dimensional MTF model of human eye is proposed and applied to designing and evaluate digital imaging system such as CCD array and digital color reproduction.

  • 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.
