Perceptual Color Contouring Detection and Quality Evaluation using Scanners

Within color reproduction issues, the reproducible color gamut and color accuracy can be classified as degree zero problems with no interaction among neighboring pixels. Image color contouring, on the other hand, occurs when perceived local color change exceeds a threshold such that observers perceive unnatural color discontinuity. Therefore, it is the color correlation within neighboring pixels that determines the existence of color contouring artifact. In this proposal, the objective is to adopt a color flatbed scanner as the measuring device to obtain color as well as spatial information. A set of test targets with smooth geometrical color variation covering various cross sections in the color space are created and printed on different printing systems. Finally, an algorithm to identify the location color contouring is proposed.

  • 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.
