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 ...

Quantifying biomechanical motion using Procrustes motion analysis
Journal of Biomechanics, 2007The ability to quantify and compare the movements of organisms is a central focus of many studies in biology, anthropology, biomechanics, and ergonomics. However, while the importance of functional motion analysis has long been acknowledged, quantitative methods for identifying differences in motion have not been widely developed.

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. Dynamical equations are written for this model including both viscous

Continuous Dynamic Spinal Motion Analysis
Spine, 2006Continuous dynamic lumbar intervertebral flexion-extension is assessed by a videofluoroscopy with a new auto-tracking system.To develop and validate a new method for the continuous assessment of lumbar kinematics.Instability of the lumbar spine is thought to be associated with low back pain, but the diagnosis remains difficult.

Adaptive Motion Data Representation with Repeated Motion Analysis
IEEE Transactions on Visualization and Computer Graphics, 2011In this paper, we present a representation method for motion capture data by exploiting the nearly repeated characteristics and spatiotemporal coherence in human motion. We extract similar motion clips of variable lengths or speeds across the database. Since the coding costs between these matched clips are small, we propose the repeated motion analysis

Visual Mechanisms of Motion Analysis and Motion Perception
Annual Review of Psychology, 2004Psychophysical experiments on feature tracking suggest that most of our sensitivity to chromatic motion and to second-order motion depends on feature tracking. There is no reason to suppose that the visual system contains motion sensors dedicated to the analysis of second-order motion.

Motion Analysis for Cooking Motion Recognition
2016 12th International Conference on Signal-Image Technology & Internet-Based Systems (SITIS), 2016To construct a cooking motion model, we needed to analyze features of cooking motions. Our aim was to recognize cooking motions by tracking the motions of the joints of a cook's arms with a three-dimensional depth sensor. To recognize the motions, we needed to analyze their features of interest.

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.
