Global illumination of non-Euclidean spaces [PDF]

Computers & Graphics, 2020
This paper presents a path tracer algorithm to compute the global illumination of non-Euclidean manifolds. We use the 3D torus as an example.

Spectrum decomposition in Gaussian scale space for uneven illumination image binarization.

PLoS ONE, 2021
Although most images in industrial applications have fewer targets and simple image backgrounds, binarization is still a challenging task, and the corresponding results are usually unsatisfactory because of uneven illumination interference.

Energy-Reduced Arrhythmia Termination Using Global Photostimulation in Optogenetic Murine Hearts

Frontiers in Physiology, 2018
Complex spatiotemporal non-linearity as observed during cardiac arrhythmia strongly correlates with vortex-like excitation wavelengths and tissue characteristics.

Progressive Photon Elimination With a Status Tree

IEEE Access, 2020
We describe a modified progressive photon mapping (PPM) method applied with sample elimination, referred to as progressive photon elimination, to pursue accurate results and accelerated iterations.

Global Illumination Shadow Layers [PDF]

Computer Graphics Forum, 2019
AbstractComputer graphics artists often resort to compositing to rework light effects in a synthetic image without requiring a new render. Shadows are primary subjects of artistic manipulation as they carry important stylistic information while our perception is tolerant with their editing.

Global Illumination-Aware Stylised Shading

, 2021
Our aim is to convert an object's appearance to an arbitrary colour considering the light scattering in the entire scene, which is often called the global illumination.
