Surgical Endoscopy, 2001
Background: The ability to make an objective evaluation of a surgeon's operative ability remains an elusive goal. In this study, we used motion analysis as a measure of dexterity in the performance of a simulated operation. Methods: Fifteen surgeons performed a total of 45 laboratory-based laparoscopic cholecystectomies on a cadaveric porcine liver ...

Determining the principles of human motion by combining motion analysis and motion synthesis
2009 9th IEEE-RAS International Conference on Humanoid Robots, 2009Synthesizing of human motion is one of the challenges in humanoid robotics research. Interested in the construction of humanoid service robots exhibiting human-like movements research is following different ways. This paper is going along with the idea of determining the principles of human motor control in order to understand the generation of human ...

Functional analysis of grasping motion
2013 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2013This paper presents a novel grasping motion analysis technique based on functional principal component analysis (fPCA). The functional analysis of grasping motion provides an effective representation of grasping motion and emphasizes motion dynamic features that are omitted by classic PCA-based approaches.

Motions and pattern analysis: harmonic analysis on motion groups and their homogeneous spaces
IEEE Transactions on Systems, Man, and Cybernetics, 1991Fourier-like transforms that are defined on several groups of motions on the plane and on the plane itself (viewed as the homogeneous space of these motion groups) are presented. These transforms should have many applications in the area of pattern recognition, detection, and the representation of motions in pattern analysis.

Hierarchical analysis of visual motion
IEEE Transactions on Systems, Man, and Cybernetics, 1992A hierarchical data structure for analyzing visual motion is presented. Although the literature on perception is abundant with studies on visual motion, none of the studies investigated the importance of a hierarchical model in the analysis of visual motion. The model was implemented on a supercomputer (Cyber 205).

Motion analysis in cervical dystonia
Neurological Sciences, 2008To evaluate kinematic features in cervical dystonia (CD) patients by means of a motion analysis system (Fastrack-Polhemus, Colchester VT, USA).Small study sample.Ambulatory care.15 CD patients and 10 healthy subjects.Not applicable.Posture at rest and voluntary movements in both groups. Posture at rest in CD patients was impaired in all planes; only 20%

A Multibody Motion Stability Analysis
Multibody System Dynamics, 1999The authors use AUTOLEV, a symbol manipulation computer program, to study the stability of a class of multibody systems. The advantages of AUTOLEV for this purpose is discussed. The paper could be useful to analysts working with large systems, both specifically and in general.

Abnormal crowd motion analysis
2009 IEEE International Conference on Robotics and Biomimetics (ROBIO), 2009Video surveillance in crowded areas is becoming more and more significant for public security. This paper presents a method for the detection of abnormality in crowded scenes based on the crowd motion characteristics. These characteristics includes the crowd kinetic energy and the motion directions.

Motion analysis for face capturing
7th International Conference on Control, Automation, Robotics and Vision, 2002. ICARCV 2002., 2004Face recognition is one of the most suitable biometric methods for supporting systems that require high security. The success of a face recognition system involves more than just the comparison algorithm. Face data acquisition is the first step towards developing face recognition systems. The accuracy of a face recognition system greatly depends on the
