Estimation of Actual Image in a Brain Using Measured Results of Distributions of the Color Sensitivity and the Resolution in the Human Vision
Abstract:The resolution achieved by human vision should not be uniform, considering the non-even distribution of cone cells on the retina. However, details of resolution distribution remain unknown: it remains unclear what kind of images are formed on the virtual screen in the brain. This study should indicate the minimum image set necessary for non-degraded image recognition. Subjective tests are carried out in order to confirm human sensitivity to degraded images with decreased chroma values in the circumferential area. The subjects are asked to choose the degree of image degradation from among five levels. Another experiment is carried out to clarify the resolution distribution in human vision: eye mark tracks are recorded in the task of searching for a target pattern from among a pattern array projected on a screen. A resolution distribution is obtained from these eye marks. The distributions of resolution and the sensitivity to chroma level are shown to well match the distribution of cone cells on the retina. The actual image in the brain can be estimated from these distributions.

For more than 30 years, IS&T's series of digital printing conferences have been the leading forum for discussion of advances and new directions in 2D and 3D printing technologies. A comprehensive, industry-wide conference that brings together industry and academia, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems?particularly those involved with additive manufacturing and fabrication?including bio-printing, printed electronics, page-wide, drop-on-demand, desktop and continuous ink jet, toner-based systems, and production digital printing, as well as the engineering capability, optimization, and science involved in these fields. In 2016, the conference changed its name formally to Printing for Fabrication to better reflect the content of the meeting and the evolving technology of printing.
