Capturing and reconstructing real world environments in 3D has broad areas of application including virtual reality, entertainment, archiving, simulation, and training. Geometry-based methods typically estimate the geometry of the environment based on ...

In this work we present an inexpensive method of exploring a large immersive virtual environment (VE). More specifically, we describe a method of physically leaning to explore a VE on a Nintendo Wii Fit Balance Board, Wii-Leaning. In two experiments ...

Saliency detection is a key component of content-aware image processing, such as image retargeting. The speciality of cartoon images make the existing algorithms hard to get excellent results. In this paper, we propose a new method to detect saliency ...

This paper presents a saliency based bag-of-phrases (Saliency-BoP for short) method for image retrieval. It combines saliency detection with visual phrase construction to extract bag-of-phrase features. To achieve this, the method first detects salient ...

An increase number of gesture sensors and AR(augmented reality) displays are emerging these years. There are more and more study working on spatial interaction. In this work, we focus on evaluating the feasibility of hand-based interaction designed for ...

This paper proposes an efficient method to extract the geometric characteristics of meshes, to make an assertive choice of an acceleration structure for ray tracing in real-time. This method automatically decides the best acceleration structure type for ...

Most of current background subtraction algorithms have issues of ghost and foreground aperture when they process the crowded video sequences in the outdoor scenes. In this paper we present a novel method based on the pixel state to solve the issues. ...

Retargeting three-dimensional facial expressions is a hot issue in the field of computer science and technology, the animation industry and realistic social network. In this paper, we present a retargeting method of 3D facial expressions through the ...

In this paper, an automatic framework of facial expression analysis focusing on quantitative intensity illustration is proposed. Quantitative intensity variation could be extracted during the whole period of facial expressions, from neutral state to ...

Wrinkle is the most significant dynamic effects on cloth simulation. Although clothes with wrinkles make graphics more believable, many real time graphics systems make compromises on it because of time and space consuming.

A region division based method ...

A modified RRF[Ren et al. 2013] rendering method called TsRRF is presented in this paper, which support global illumination in realtime for scenes with moving transparent objects. The key idea of this method is to augment the map between object and ...

Multiple Importance Sampling (MIS) technique has been widely used in Computer Graphics in rendering algorithms. MIS is based on weighting several sampling techniques into a single estimator. When the combination weights are taken such that the sample ...

We propose a collaborative web interior design system that assists multi-users in real time house editing and furniture arrangement. Our system incorporates the transparent adaptation layer, which is an important network protocol, to achieve the online ...

Depth of Field is an important factor to synthesize realistic photography effects. In our paper, we discuss a new image-based approach that can synthesize DoF effects without user iterations. Our approach can produce the based saliency maps with ...
