SAR: Stroke Authorship Recognition

Are simple strokes unique to the artist or designer who renders them? If so, can this idea be used to identify authorship or to classify artistic drawings? Also, could training methods be... Read more »

A Survey of Real-Time Crowd Rendering

In this survey we review, classify and compare existing approaches for real-time crowd rendering. We first overview character animation techniques, as they are highly tied to crowd rendering performance, and then we... Read more »

Detection of Geometric Temporal Changes in Point Clouds

Detecting geometric changes between two 3D captures of the same location performed at different moments is a critical operation for all systems requiring a precise segmentation between change and no-change regions. Such... Read more »

Line-Drawing Video Stylization

We present a method to automatically convert videos and CG animations to stylized animated line drawings. Using a data-driven approach, the animated drawings can follow the sketching style of a specific artist.... Read more »

Two Simple Methods for Improving a Triangle Mesh Surface

We present two simple and efficient local methods that reposition vertices of a triangle mesh surface with the goal of producing good triangle shapes while preserving the enclosed volume and sharp features.... Read more »

Pairwise Registration by Local Orientation Cues

Inspired by recent work on robust and fast computation of 3D Local Reference Frames (LRFs), we propose a novel pipeline for coarse registration of 3D point clouds. Key to the method are:... Read more »

A Hierarchical Approach for Regular Centroidal Voronoi Tessellations

In this paper, we consider Centroidal Voronoi Tessellations (CVTs) and study their regularity. CVTs are geometric structures that enable regular tessellations of geometric objects and are widely used in shape modelling and... Read more »

Planar Shape Detection and Regularization in Tandem

We present a method for planar shape detection and regularization from raw point sets. The geometric modelling and processing of man-made environments from measurement data often relies upon robust detection of planar... Read more »

Example-Driven Procedural Urban Roads

Synthesizing and exploring large-scale realistic urban road networks is beneficial to 3D content creation, traffic animation and urban planning. In this paper, we present an interactive tool that allows untrained users to... Read more »

Real-Time Rendering Techniques with Hardware Tessellation

Graphics hardware has progressively been optimized to render more triangles with increasingly flexible shading. For highly detailed geometry, interactive applications restricted themselves to performing transforms on fixed geometry, since they could not... Read more »
