Photometric Stabilization for Fast-forward Videos
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
Videos captured by consumer cameras often exhibit temporal variations in color and tone that are caused by camera autoadjustments like white-balance and exposure. When such videos are sub-sampled to play fast-forward, as ...
Efficient Gradient-Domain Compositing Using an Approximate Curl-free Wavelet Projection
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
Gradient-domain compositing has been widely used to create a seamless composite with gradient close to a composite gradient field generated from one or more registered images. The key to this problem is to solve a Poisson ...
Real-time Texture Synthesis and Concurrent Random-access Rendering for Low-cost GPU Chip Design
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
Numerous algorithms have been researched in the area of texture synthesis. However, it remains difficult to design a low-cost synthesis scheme capable of generating high quality results while simultaneously achieving ...
An Error Estimation Framework for Many-Light Rendering
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
The popularity of many-light rendering, which converts complex global illumination computations into a simple sum of the illumination from virtual point lights (VPLs), for predictive rendering has increased in recent years. ...
Forward Light Cuts: A Scalable Approach to Real-Time Global Illumination
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
We present Forward Light Cuts, a novel approach to real-time global illumination using forward rendering techniques. We focus on unshadowed diffuse interactions for the first indirect light bounce in the context of large ...
Retailoring Box Splines to Lattices for Highly Isotropic Volume Representations
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
3D box splines are defined by convolving a 1D box function with itself along different directions. In volume visualization, box splines are mainly used as reconstruction kernels that are easy to adapt to various sampling ...
Geometry and Attribute Compression for Voxel Scenes
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
Voxel-based approaches are today's standard to encode volume data. Recently, directed acyclic graphs (DAGs) were successfully used for compressing sparse voxel scenes as well, but they are restricted to a single bit of ...
MCFTLE: Monte Carlo Rendering of Finite-Time Lyapunov Exponent Fields
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
Traditionally, Lagrangian fields such as finite-time Lyapunov exponents (FTLE) are precomputed on a discrete grid and are ray casted afterwards. This, however, introduces both grid discretization errors and sampling errors ...
