Recent Advances in Transient Imaging: A Computer Graphics and Vision Perspective
It addresses the problem of leveraging temporal information for graphics and vision applications, but it is incremental as it surveys existing advances.
The paper reviews transient imaging techniques that capture light transport at high temporal resolutions to enable applications like seeing around corners and detecting objects in scattering media, highlighting recent advances in capture, analysis, and simulation.
Transient imaging has recently made a huge impact in the computer graphics and computer vision fields. By capturing, reconstructing, or simulating light transport at extreme temporal resolutions, researchers have proposed novel techniques to show movies of light in motion, see around corners, detect objects in highly-scattering media, or infer material properties from a distance, to name a few. The key idea is to leverage the wealth of information in the temporal domain at the pico or nanosecond resolution, information usually lost during the capture-time temporal integration. This paper presents recent advances in this field of transient imaging from a graphics and vision perspective, including capture techniques, analysis, applications and simulation.
