Human Factors: The Journal of the Human Factors and Ergonomics Society, 1973
This paper presents an analysis of swimming motion with specific attention given to the flutter kick, the breast-stroke kick, and the breast stroke. The analysis is completely theoretical. It employs a mathematical model of the human body consisting of frustrums of elliptical cones.

Using motion analysis techniques for motion retargeting
Proceedings Sixth International Conference on Information Visualisation, 2003This paper proposes a new approach for motion retargeting, i.e., adjusting motion-capture data to different characters and scenes. For achieving universality, the existing retargeting techniques often become absolutely impractical for most of real-life applications.

Motion analysis: model selection and motion segmentation
12th International Conference on Image Analysis and Processing, 2003.Proceedings., 2004A new model selection criterion based on physical characteristics of underlying motion models is proposed. The proposed criterion is then incorporated in a robust motion segmentation scheme, which is based upon robust least K-th order statistical model fitting. The proposed model criterion has been compared with many other competing techniques and it’s

Nonrigid Motion Analysis: Articulated and Elastic Motion
Computer Vision and Image Understanding, 1998Motion of physical objects in the world is, in general, nonrigid. In robotics and computer vision, the motion of nonrigid objects is of growing interest to researchers from a wide spectrum of disciplines. The nonrigid objects being studied may be generally categorized into three groups according to the degree of deformation of body parts: articulated ...

Veterinary Clinics of North America: Equine Practice, 1991
Time magnification in motion photography allows the observation of events in the stride cycle that normally are beyond the resolution of the human eye. Quantitative analysis goes a stage further by measuring the stride in terms of timing, distance, and angular variables.

A fundamental assumption made in formulating optical flow algorithms is that motion at any point in an image can be represented as a single pattern component undergoing a simple translation: even complex motion will ‘look like’ uniform displacement when viewed through a sufficiently small window.

Human Motion Analysis: A Review
Computer Vision and Image Understanding, 1999Human motion analysis is receiving increasing attention from computer vision researchers. This interest is motivated by a wide spectrum of applications, such as athletic performance analysis, surveillance, man-machine interfaces, content-based image storage and retrieval, and video conferencing. The paper gives an overview of the various tasks involved

Non-rigid motion analysis: Isometric motion
CVGIP: Image Understanding, 1992Summary: We consider the shape-from-motion problem for objects in 3-space that undergo isometric motions. Assuming we known the shape of an object before an isometric motion, we show that we can use before and after monocular images to obtain arbitrarily good approximations to both shape and motion parameters.

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 ...

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.
