Abstract
As the performance of electronic display systems continues to increase, the limitations of current signal coding methods become increasingly apparent. With bit-depth limitations set by industry standard interfaces, a more efficient coding system is desired to allow image quality to increase without requiring expansion of legacy infrastructure bandwidth. A good approach to this problem is to let the human visual system determine the quantization curve used to encode video signals. In this way, optimal efficiency is maintained across the luminance range of interest, and the visibility of quantization artifacts is kept to a uniformly small level.

Scott Miller
bio
Scott Miller is a senior member of the technical staff at Dolby Laboratories where he serves in the Image Technology Research group. He received a B.S. in electrical engineering from Cornell University and has spent nearly 30 years working in the video industry. He started in post-production and systems design before joining Panasonic Research where he turned his attention to hardware and algorithm design for several broadcast and consumer devices. He moved to Dolby in 2005 where he continues to specialize in image display technology and video signal processing. Along the way, he has had the privilege of helping to develop two Emmy award winning products: Panasonic's Universal Video Format Converter and Dolby's Professional Reference Monitor
Mahdi Nezamabadi
bio
Mahdi Nezamabadi received a Ph. D. in Imaging Science from the Rochester Institute of Technology in 2008. He was a member of the Spectral Imaging Group of the Munsell Color Science Laboratory and worked on design and implementation of an accurate end-to-end spectral color reproduction system. He also studied the effect of image size on the color appearance of image reproductions. Dr. Nezamabadi joined Dolby Laboratories in 2007. Presently, he is investigating image quality and color management of HDR video. His interests are appearance of softcopy color reproduction, video color processing, image quality, and phenomena such as adaptation and metamerism.
Scott Daly
bio
Scott Daly received a B.S. EE degree in 1980 from North Carolina State University, and then worked with early highresolution laser scanning systems at Photo Electronics Corp. in West Palm Beach, FL. Shifting from hardware to wetware, he obtained an M.S. in bioengineering from the University of Utah in 1984, completing a neurophysiology thesis on the temporal processing of cone photoreceptors. Daly then worked in the Imaging Science Division at Eastman Kodak in the fields of image compression, image fidelity models, and image watermarking. Next, he worked at Sharp Laboratories of America in Washington State, where he led a group on display algorithms. — Becoming a research fellow, Daly applied visual models towards digital video and displays, with publications on spatiotemporal and motion imagery, human interaction with wall-sized displays, and stereoscopic displays. These topics led him to join Dolby Laboratories in 2010 to focus on overall fundamental perceptual issues, and efforts to preserve artistic intent throughout the entire video path to reach the viewer. Daly received an Otto Schade Award from SID in 2011 for Applied Perception and a team Emmy Award in ′89-90 for a Video Transceiver as used in a prominent news event. He is currently a member of IEEE, SPIE, and SID.
