On 6 September 2023, Assoc. Prof. Dr. Nameer Hashim Qasim authored a significant paper titled “Comparison of Metamerism Estimates in Video Paths using CAM’s Models” which was published in the IEEE Xplore Journal and has been indexed by Scopus. The abstract of the paper delineates the challenges of metamerism in multimedia and telecommunication channels. The research primarily emphasizes the terminal devices in the end-to-end trajectory. The paper contrasts the evaluations done using traditional color representation coordinate systems with those of contemporary color models like CAM16, CAM20u, and ZCAM. The research showcases numerical disparities in the data acquired under uniform input circumstances. It also presents statistical data regarding metamer estimates via Mac Adam ellipses. The study reveals that colors’ spectral compositions might be perceived identically (as suggested by McAdam’s data). However, their count may vary upon processing. The research findings indicate that these differences could escalate up to 15%. Notably, when the ZCAM models are utilized, a larger color palette is considered during transmission. This aids in minimizing the impact of metamerism on color portrayal. The paper can be accessed through this (https://ieeexplore.ieee.org/document/10238685 )
