Open Access Scene Appearance Change As Framerate Approaches Infinity

The primary goal in most uses of a camera is not to capture properties of light, but to use light to construct a model of the appearance of the scene being photographed. That model should change over time as the scene changes, but how does it change over different timescales? At low framerates, there often are large changes between temporally adjacent images, and many are attributed to motion. However, as the scene appearance is sampled in ever finer time intervals, the changes in the scene become simpler and eventually insignificant compared to noise in the sampling process (e.g., photon shot noise). Thus, increasing the temporal resolution of the scene model can be expected to produce a decreasing amount of additional data. This property can be leveraged to allow virtual still exposures, or video at other framerates, to be computationally extracted after capture of a high-temporal-resolution scene model, providing a variety of benefits. The current work attempts to quantify how scene appearance models change over time by examining properties of high-framerate video, with the goal of characterizing the relationship between temporal resolution and effectiveness of data compression.

More about this publication?
  • For more than 30 years, the Electronic Imaging Symposium has been serving those in the broad community - from academia and industry - who work on imaging science and digital technologies. The breadth of the Symposium covers the entire imaging science ecosystem, from capture (sensors, camera) through image processing (image quality, color and appearance) to how we and our surrogate machines see and interpret images. Applications covered include augmented reality, autonomous vehicles, machine vision, data analysis, digital and mobile photography, security, virtual reality, and human vision. IS&T began sole sponsorship of the meeting in 2016. All papers presented at EIs 20+ conferences are open access.

    Please note: For purposes of its Digital Library content, IS&T defines Open Access as papers that will be downloadable in their entirety for free in perpetuity. Copyright restrictions on papers vary; see individual paper for details.
