Team formation with realistic crowd simulation behaviour is a challenge in computer graphics, multi-agent control and social simulation. In this paper, we propose a framework of crowd formation via hierarchical planning, which includes cooperative-task, coordinated-behaviour and action-control planning. In cooperative-task planning, we improve the grid potential field to achieve global ...

This paper presents a novel base-points-driven shape correspondence (BSC) approach to extract skeletons of articulated objects from 3D mesh shapes. The skeleton extraction based on BSC approach is more accurate than the traditional direct skeleton extraction methods. Since 3D shapes provide more geometric information, BSC offers the consistent information between ...

Touchless interaction has received considerable attention in recent years with benefit of removing barriers of physical contact. Several approaches are available to achieve mid-air interactions. However, most of these techniques cause discomfort when the interaction method is not direct manipulation. In this paper, gestures based on unimanual and bimanual interactions ...

The analysis of cerebrovascular shape is important for the diagnose and pathologic identification. But as the limitation of the segmentation algorithm, the complete cerebrovascular volume data are difficult to obtain. So the triangle mesh of the vessel model generated for the medical images may appear many gaps. In the paper, ...

Ancient Chinese architecture from the Song dynasty is a prominent example of the ancient oriental architectures. The cai-fen system was a module system used for the carpentry of Song architectures, which was specified by the governmental manual, the Yingzao Fashi (State Building Standards) compiled by Li Jie [1103]. We present ...

Non-rigid 3D shape correspondence is a fundamental and challenging problem. Isometric correspondence is an important topic because of its wide applications. But it is a NP hard problem if detecting the mapping directly. In this paper, we propose a novel approach to find the correspondence between two nearly isometric shapes. ...

In shape analysis, scaling factors have a great influence on the results of non-rigid shape retrieval and correspondence. In order to eliminate the effects of scale ambiguity, a method with scale-invariant property is required for shape analysis. Previous mapping method only focus on the isometric conditions. In this paper, a ...

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 motion of facial feature points based on Kinect. Firstly, we use a cheap ...

Craniofacial reconstruction aims to estimate an individual's facial appearance from its skull. It can be applied in many multimedia services such as forensic medicine, archaeology, face animation etc. In this paper, a statistical learning based method is proposed for 3D craniofacial reconstruction. In order to well represent the craniofacial shape ...

The process of making skeleton for character animation is a long-winded task requiring manual tweaking. This paper presents a novel method to generate an automatic robust animated skeleton from 3D human geometric model. First, our method contracts the mesh by applying Laplacian-based mesh contractions with constraints. The mesh contraction process ...

Skull identification is an important subject for research in forensic medicine. Current research can be divided into two categories: 1) craniofacial superimposition and 2) craniofacial reconstruction. Both categories rely essentially on the accurate extraction and representation of the intrinsic relationship between the skull and face in terms of the morphology, ...
