Temporally Coherent Local Tone Mapping of HDR Video

Temporally Coherent Local Tone Mapping of HDR Video

by Martina Megaro | Nov 19, 2014 | Video Processing, Visual Computing

Temporally Coherent Local Tone Mapping of HDR Video   Recent subjective studies showed that current tone mapping operators either produce disturbing temporal artifacts, or are limited in their local contrast reproduction capability. We address both of these issues and...
Residual Ratio Tracking for Estimating Attenuation in Participating Media

Residual Ratio Tracking for Estimating Attenuation in Participating Media

by Martina Megaro | Nov 19, 2014 | Rendering, Visual Computing

Residual Ratio Tracking for Estimating Attenuation in Participating Media   We present ratio tracking and residual tracking, two complementary techniques that can be combined into an efficient, unbiased estimator for evaluating transmittance in complex heterogeneous...
Frequency-Based Creation and Editing of Virtual Terrain

Frequency-Based Creation and Editing of Virtual Terrain

by Martina Megaro | Nov 13, 2014 | Animation, Visual Computing

Frequency-Based Creation and Editing of Virtual Terrain   We present a sketch-based toolset for asset-guided creation and intuitive editing of virtual terrains, allowing the manipulation of both elevation maps and 3D meshes, and exploiting a layer-based interface....
High-Speed Object Tracking Using an Asynchronous Temporal Contrast Sensor

High-Speed Object Tracking Using an Asynchronous Temporal Contrast Sensor

by Martina Megaro | Oct 8, 2014 | Video Processing, Visual Computing

High-Speed Object Tracking Using an Asynchronous Temporal Contrast Sensor   In this paper, we approach this problem by asynchronously recording local contrast change at high speed, using a type of visual capture device called a Dynamic Vision Sensor (DVS). October 8,...
Continuous Synchronization for LED-to-LED Visible Light Communication Networks

Continuous Synchronization for LED-to-LED Visible Light Communication Networks

by Martina Megaro | Sep 17, 2014 | Visual Computing, Wireless Communication and Ubiquitous Computing

Continuous Synchronization for LED-to-LED Visible Light Communication Networks   We present and evaluate a physical layer and a distributed, contention-based medium access control protocol that enables reliable communication over room range distances; both are...
