Global Texture Mapping for Dynamic Objects
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
We propose a novel framework to generate a global texture atlas for a deforming geometry. Our approach distinguishes from prior arts in two aspects. First, instead of generating a texture map for each timestamp to color a ...
Deep HDR Video from Sequences with Alternating Exposures
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
A practical way to generate a high dynamic range (HDR) video using off-the-shelf cameras is to capture a sequence with alternating exposures and reconstruct the missing content at each frame. Unfortunately, existing ...
Computing Surface PolyCube-Maps by Constrained Voxelization
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
We present a novel method to compute bijective PolyCube-maps with low isometric distortion. Given a surface and its preaxis- aligned shape that is not an exact PolyCube shape, the algorithm contains two steps: (i) construct ...
An Analysis of Region Clustered BVH Volume Rendering on GPU
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
We present a Direct Volume Rendering method that makes use of newly available Nvidia graphics hardware for Bounding Volume Hierarchies. Using BVHs for DVR has been overlooked in recent research due to build times potentially ...
Gradient Outlier Removal for Gradient-Domain Path Tracing
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
We present a new outlier removal technique for a gradient-domain path tracing (G-PT) that computes image gradients as well as colors. Our approach rejects gradient outliers whose estimated errors are much higher than those ...
An Efficient Solution to Structured Optimization Problems using Recursive Matrices
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
We present a linear algebra framework for structured matrices and general optimization problems. The matrices and matrix operations are defined recursively to efficiently capture complex structures and enable advanced ...
A Subspace Method for Fast Locally Injective Harmonic Mapping
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
We present a fast algorithm for low-distortion locally injective harmonic mappings of genus 0 triangle meshes with and without cone singularities. The algorithm consists of two portions, a linear subspace analysis and ...
Shadow Inpainting and Removal Using Generative Adversarial Networks with Slice Convolutions
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
In this paper, we propose a two-stage top-down and bottom-up Generative Adversarial Networks (TBGANs) for shadow inpainting and removal which uses a novel top-down encoder and a bottom-up decoder with slice convolutions. ...
Reliable Rolling-guided Point Normal Filtering for Surface Texture Removal
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
Semantic surface decomposition (SSD) facilitates various geometry processing and product re-design tasks. Filter-based techniques are meaningful and widely used to achieve the SSD, which however often leads to surface ...
Interactive Curation of Datasets for Training and Refining Generative Models
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
We present a novel interactive learning-based method for curating datasets using user-defined criteria for training and refining Generative Adversarial Networks. We employ a novel batch-mode active learning strategy to ...
