CP7 researcher Steven Le Moan successfully completes his role as Experienced Research (ER1) in the CP7 project. Apart from mentoring and training activites for ESRs in the project Steven mainly worked on image quality in spectral imaging. With good support from Dr. Philipp Urban and CP7 consortium, Steven investigated spectral image quality assessment, looking at how the perception of reproduction artifacts changes with viewing conditions. Essentially he took an existing full-reference image quality metric for colour images and developed it into a fairly simple scheme to deal with multiple conditions of illumination (e.g. daylight and candle light). Through his work he was also able to identify some redundancies in the perception of achromatic artifacts and was also able to considerably reduce the numerical effort required by the metric , which is referred to as Spectral Image-Difference metric (SID). He then used these findings in the development of a new interim connection space for low-dimensional spectral image processing, which was named as LabAB. With only five dimensions, this space convey sufficient information for a good colorimetric accuracy under dozens of different light sources. Finally without really deviating from the scope of “quality as a function of viewing conditions”, he looked into High Dynamic Range image quality (HDR) and developed a new metric that he found to be significantly more versatile than what can be found in the state-of-the-art.

The meeting was attended by the graphic arts special interest group members. This meeting gave an opportunity for Steven to interact with the experts from the industry and discuss his research for guidance and expert feedback.
CP7.0 demonstration table at the Electronic Imaging 2014 demonstration session
At ST&T/SPIE EI2014 conference, the fellow researchers participated in setting up a CP7.0 project demonstration table during the demonstration session on tuesday evening, February 4, 2014. This session, during the conference provided a unique networking opportunity, a time when attendees could see the latest research in action, compare commercial products and ask questions to technically knowledgeable demonstrators.
Fellow researchers Sepideh Samadzadegan, Teun Baar and Paula Žitinski Elías prepared demonstrations describing their research activities and presented to the conference attendees during this session. The aim of these demonstrations were to present some of the research done in this project and demonstrate possible applications of the research and address key research questions in the field of multi-channel printing.
Sepideh Samadzadegan addressed the research questions about the metameric vs. spectral reproduction. She prepared and distributed spectral print samples printed with a 7 channel (CMYKRGB) printer. Each sample was perceived having the same colour in all areas under D65 illuminant while two different colours were observed under CIE A illumination.
Teun Baar addressed the research question related to reproduction of local gloss variations in printouts. There exists a strong relationship between the surface roughness of a printout and the perceived glossy appearance. Employing a 2.5D or relief printing system, the printout roughness can be controlled by manipulating the way the ink is deposited in a layer-by-layer basis. For the demonstration session, a set of samples was prepared showing how manipulating these parameters of the printing system can result in control of local gloss variations to create reflection effects in the printouts.
Paula Žitinski Elías addressed the issues related to AM halftoning and limitations when using multi-channel printing and how her work done with changing the shape of the dots helps achieve a better reproduction, compared to traditional halftone shapes currently used in the digital printing techniques. The printed results made in collaboration with Ludovic (ER2) showed obvious visual improvements when using the adapted halftone techniques, and were shown to the session attendees.
