Multiple human 3D pose estimation from multiple camera views is a challenging task in unconstrained environments. Each individual has to be matched across each view and then the body pose has to be estimated. Additionally, the body pose of every individual changes in a consistent manner over time. To address these challenges, we propose a temporally consistent 3D Pictorial Structures model (3DP...

It is well known that the use of a modular approach for modeling has many advantages: it allows the modeler to consider different parts of the model independently of one another. A modular approach to analysis is also attractive: it often dramatically decreases the complexity of the analysis task. To create Petri net models of large systems, four bottom-up techniques, consisting of sharing oper...

Fast economic growth and rapid urbanization present a challenge to the limited urban land resources of China. Specifically, they encourage a shift in the concentration on the surface of land parcels to the space above and below them. Recent development in land utilization in developed cities has broken the traditional frame of the parcel-based or 2D cadastre. The three-dimensional (3D) cadastre...

In this paper, we propose a gesture user interface for controlling a virtual camera in the 3D virtual space, which can be used to navigate the 3D virtual space by users. In the proposed mechanism, Kinect [1] is used as an input device for detecting positions of user gestures. After obtaining the positions information from Kinect, the sequences of positions are filtered to be recognized as any k...

The need for 3D diffeomorphic matching of unlabeled point sets arises in numerous registration and shape analysis oriented biomedical imaging applications. The correspondence problem coupled with the need for estimating a diffeomorphism in 3D space makes it a very difficult problem. In the present work, we show that a joint clustering and diffeomorphism estimation strategy is capable of simulta...

Marcos Novak mainly considers a type of architecture cuts loose from the expectations of logic, perspective, and laws of gravity, and has invented a set of conceptual tools for thinking about and constructing territories in cyberspace. Novak introduces the concept of "liquid architecture”, a fluid, imaginary landscape that exists only in the Digital domain. He views trans-architecture as an exp...

Among many skin color sources, hemoglobin and melanin components are regarded most significant in determining the final color of human skin. In extracting the two components, this paper proposes to use a more intuitive color model, HSV, than the RGB color space. For 3D rendering, we propose a novel method to reconstruct the fine-scale structure (normal map) of the human skin from a single highl...

Stemming from a sound mathematical framework dating back to the beginning of the 20th century, this paper introduces a novel approach for 3D face recognition. The proposed technique is based on joint differential invariants, projecting a 3D shape in a 9-dimensional space where the effect of rotation and translation is removed. As a consequence, the matching between two different 3D samples can ...

BACKGROUND This study evaluated the use of an augmented reality navigation system that provides a markerless registration system using stereo vision in oral and maxillofacial surgery. METHOD A feasibility study was performed on a subject, wherein a stereo camera was used for tracking and markerless registration. The computed tomography data obtained from the volunteer was used to create an in...

Purpose: To analyze the feasibility of three-dimensional (3D) diffusion-weighted (DW) PSIF (reversed FISP [fast imaging with steady-state free precession]) sequence in order to evaluate peripheral nerves in the elbow. Materials and Methods: Ten normal, asymptomatic volunteers were enrolled (6 men, 4 women, mean age 27.9 years). The following sequences of magnetic resonance images (MRI) of the e...
