Object Repositioning Based on the Perspective in a Single Image

We propose an image editing system for repositioning objects in a single image based on the perspective of the scene. In our system, an input image is transformed into a layer structure... Read more »

Optimized Generation of Stereoscopic CGI Films by 3D Image Warping

The generation of a stereoscopic animation film requires doubling the rendering times and hence the cost. In this paper, we address this problem and propose an automatic system for generating a stereo... Read more »

Variational Tree Synthesis

Modelling trees according to desired shapes is important for many applications. Despite numerous methods having been proposed in tree modelling, it is still a non-trivial task and challenging. In this paper, we... Read more »

Managing Spatial Selections With Contextual Snapshots

Spatial selections are a ubiquitous concept in visualization. By localizing particular features, they can be analysed and compared in different views. However, the semantics of such selections often depend on specific parameter... Read more »

A Projective Framework for Polyhedral Mesh Modelling

We present a novel framework for polyhedral mesh editing with face-based projective maps that preserves planarity by definition. Such meshes are essential in the field of architectural design and rationalization. By using... Read more »

Exemplar-Based Portrait Photograph Enhancement as Informed by Portrait Paintings

This paper proposes an approach to enhance the regional contrasts in snap-shot style portrait photographs by using pre-modern portrait paintings as aesthetic exemplars. The example portrait painting is selected based on a... Read more »

Spectral Analysis on Medial Axis of 2D Shapes

Shape analysis finds many important applications in shape understanding, matching and retrieval. Among the various shape analysis methods, spectral shape analysis aims to study the spectrum of the Laplace–Beltrami operator of some... Read more »

The PAG Crowd: A Graph Based Approach for Efficient Data-Driven Crowd Simulation

We present a data-driven method for the real-time synthesis of believable steering behaviours for virtual crowds. The proposed method interlinks the input examples into a structure we call the perception-action graph (PAG)... Read more »

Quad Layout Embedding via Aligned Parameterization

Quad layouting, i.e. the partitioning of a surface into a coarse network of quadrilateral patches, is a fundamental step in application scenarios ranging from animation and simulation to reverse engineering and meshing.... Read more »

Group-in-a-Box Meta-Layouts for Topological Clusters and Attribute-Based Groups: Space-Efficient Visualizations of Network Communities and Their Ties

An important part of network analysis is understanding community structures like topological clusters and attribute-based groups. Standard approaches for showing communities using colour, shape, rectangular bounding boxes, convex hulls or force-directed layout... Read more »
