Professor Rafal Mantiuk (Univ. of Cambridge UK): “How many pixels are too many?”

January 18, 2019 @ 4:30 pm - 5:30 pm

Department of Computer Science and Technology, University of Cambridge (UK)

Location: Packard 101

Talk Title: How many pixels are too many?

Talk Abstract: We start to lack the processing power and bandwidth to drive 8K and
high-resolution head-mounted displays. However, as the human eye and
visual system have their own limitations, the relevant question is
what spatial and temporal resolution is the ultimate limit for any
technology. In this talk, I will review the visual models of
spatio-temporal and chromatic contrast sensitivity which can explain
such limitations. Then I will show how they can be used to reduce
rendering cost in VR-applications, find more efficient encoding of
high dynamic range images and compress images in a visually lossless

Speaker’s Biography: RafaƂ K. Mantiuk is Reader (Associate Professor) at the Department
of Computer Science and Technology, University of Cambridge (UK). He
received PhD from the Max-Planck-Institute for Computer Science
(Germany). His recent interests focus on computational displays, novel
display technologies, rendering and imaging algorithms that adapt to
human visual performance and viewing conditions in order to deliver
the best images given limited resources, such as computation time,
bandwidth or dynamic range. He contributed to early work on high
dynamic range imaging, including quality metrics (HDR-VDP), video
compression and tone-mapping. Further details: http://www.cl.cam.ac.uk/~rkm38/.
