Fast separation of direct and global components of a scene using high frequency illumination
ACM Transactions on Graphics (TOG), Volume 25, Issue 3Pages 935–944https://doi.org/10.1145/1141911.1141977We present fast methods for separating the direct and global illumination components of a scene measured by a camera and illuminated by a light source. In theory, the separation can be done with just two images taken with a high frequency binary ...

Phasor Imaging: A Generalization of Correlation-Based Time-of-Flight Imaging
ACM Transactions on Graphics (TOG), Volume 34, Issue 5Article No.: 156, Pages 1–18https://doi.org/10.1145/2735702In correlation-based time-of-flight (C-ToF) imaging systems, light sources with temporally varying intensities illuminate the scene. Due to global illumination, the temporally varying radiance received at the sensor is a combination of light received ...

Scattering: Acquisition, Modeling, and Rendering
IEEE Computer Graphics and Applications (ICGA), Volume 33, Issue 3Pages 32–33https://doi.org/10.1109/MCG.2013.46Over the past few years, the landscape of volumetric-scattering techniques has evolved rapidly. The articles in this special issue highlight how these techniques are expanding our abilities to author increasingly complex visual appearance.

Real-time volumetric shadows using 1D min-max mipmaps
I3D '11: Symposium on Interactive 3D Graphics and GamesPages 39–46 PAGE@7https://doi.org/10.1145/1944745.1944752Light scattering in a participating medium is responsible for several important effects we see in the natural world. In the presence of occluders, computing single scattering requires integrating the illumination scattered towards the eye along the ...

A hierarchical volumetric shadow algorithm for single scattering
SIGGRAPH ASIA '10: ACM SIGGRAPH Asia 2010 papersArticle No.: 178, Pages 1–10https://doi.org/10.1145/1866158.1866200Volumetric effects such as beams of light through participating media are an important component in the appearance of the natural world. Many such effects can be faithfully modeled by a single scattering medium. In the presence of shadows, rendering ...

Detection and Analysis of Anisotropic Scattering in SAR Data
Multidimensional Systems and Signal Processing (MULT), Volume 14, Issue 1-3Pages 49–82https://doi.org/10.1023/A:1022268908156Scattering from man-made objects in SAR imagery exhibits aspect and frequency dependencies which are not well modeled by standard SAR imaging techniques. If ignored, these deviations will reduce recognition performance due to the model mismatch, but ...
