Improved all-sky search method for continuous gravitational waves from unknown neutron stars in binary systems [article]

P. B. Covas, R. Prix
2022 arXiv   pre-print
In this paper, we present a new all-sky binary search method, BinarySkyHouℱ, which extends and improves upon the earlier BinarySkyHough method, and which was the basis for a recent search (Covas et al.  ...  Consequently, very few search algorithms and implementations exist for these sources, and only a handful of such searches have been performed so far.  ...  ACKNOWLEDGMENTS This work has utilized the ATLAS computing cluster at the MPI for Gravitational Physics Hannover.  ...

Rectilinear texture warping for fast adaptive shadow mapping

Paul Rosen
2012 Proceedings of the ACM SIGGRAPH Symposium on Interactive 3D Graphics and Games - I3D '12  
RTW images consist of a conventional texture paired with two 1-D warping maps that form a rectilinear grid defining the variation in sampling rate.  ...  This paper introduces Rectilinear Texture Warping (RTW) for efficiently generating adaptive shadow maps.  ...  We would also like to thank the Voicu Popescu and Josh Levine for useful feedback, in addition to all of the reviewers.  ...

Neural Alignment for Face De-pixelization [article]

Maayan Shuvi, Noa Fish, Kfir Aberman, Ariel Shamir, Daniel Cohen-Or
2020 arXiv   pre-print
There is no need for explicit temporal coherency loss as it is maintained implicitly by the alignment of neighboring frames and reconstruction.  ...  We present a simple method to reconstruct a high-resolution video from a face-video, where the identity of a person is obscured by pixelization.  ...  Using the aligned surrounding stack of frames also provides implicit temporal coherence for consecutive frames, and eliminates the need for an explicit temporal coherence loss.  ...

Fast Ray Sorting and Breadth-First Packet Traversal for GPU Ray Tracing

Kirill Garanzha, Charles Loop
2010 Computer graphics forum (Print)  
These stages include: ray sorting into coherent packets, creation of frustums for packets, breadth-first frustum traversal through a bounding volume hierarchy for the scene, and localized ray-primitive  ...  We decompose a standard ray tracing algorithm into several data-parallel stages that are mapped efficiently to the massively parallel architecture of modern GPUs.  ...  Acknowledgments We thank the University of Utah for the Fairy scene, Anat Grynberg and Greg Ward for Conference scene and Marko Dabrovic for Sponza Atrium scene.  ...

TemporalUV: Capturing Loose Clothing with Temporally Coherent UV Coordinates [article]

You Xie, Huiqi Mao, Angela Yao, Nils Thuerey
2022 arXiv   pre-print
We implemented a differentiable pipeline to learn UV mapping between a sequence of RGB inputs and textures via UV coordinates.  ...  We propose a novel approach to generate temporally coherent UV coordinates for loose clothing. Our method is not constrained by human body outlines and can capture loose garments and hair.  ...  To better understand the relationship between I t , P r t and T t , we visualize UV mapping results for a synthetic grid texture W(T grid , ω I (P r t )) in Figure 2b .  ...

Decoupled sampling for graphics pipelines

Jonathan Ragan-Kelley, Jaakko Lehtinen, Jiawen Chen, Michael Doggett, Frédo Durand
2011 ACM Transactions on Graphics  
We present extensions of two modern graphics pipelines to support decoupled sampling: a GPU-style sort-last fragment architecture, and a Larrabee-style sort-middle pipeline.  ...  It can be thought of as a generalization of multisample antialiasing (MSAA) to support complex and dynamic mappings from visibility to shading samples, as introduced by motion and defocus blur and adaptive  ...  This work was supported by Singapore-MIT Gambit and a grant from Intel Corp.

on the floor), as well as a pipeline to extract such a map from a single RGB image.  ...  We quantitatively evaluate our results, showing that we clearly outperform a dense baseline approach, and argue that scene maps provide a useful representation for abstract indoor scene understanding.  ...  The generated scenes are then rendered using an OpenGL setup with a simple Phong shading model. For each scene, we also generate the scene map, semantic labeling, and depth ground truth.  ...
