    "abstract": "The screen size and the resolution of the displays available to the consumer market have been steadily increasing. According to established vision science, there are limits to the human visual system for the perceptibility of resolution at typical viewing distances. This paper discusses a subjective evaluation that was performed to assess the perceptual difference between UHD-1/4K and UHD-2/8K for various types of content on an UHD-2/8K consumer display. It also performs a detailed frequency and visibility analysis of the content to determine the characteristics of the most perceptual content and establishes a relationship between the subjective test results and the vision science.",

        "bio": "Michael D. Smith has been a digital imaging and intellectual property consultant since 2003. He is currently the co-editor of the Joint Photographic Experts Group (JPEG) 2000 high-throughput image compression standard. In 2018, he received a screen credit for his work on Mary Poppins Returns which was related to the color science involved in integrating a traditional 2D animation workflow with a modern ACES production pipeline. From 2013 to 2015, he was the co-chair of Blu-ray Disc Association’s ultrahigh-definition task force (UHDTF) Video Subgroup, which defined the video-related requirements for the UHD Blu-ray disc format. His work on more than 35 intellectual property matters related to infringement and validity of patents has resulted in payments of approximately $1.7 billion. He was the editor of the book “3D Cinema and Television Technology: The First 100 Years” published by SMPTE in 2011. He received the BS and MS degrees in electrical engineering from the University of California at Los Angeles (UCLA), Los Angeles, CA, in 2001 and 2004, respectively.",
