background: the purpose of the present study was to examine the reliability of scapular kinematic measurements using motion analysis system in subjects with and without general hypermobility syndrome. methods: a methodological study was designed to assess the reliability of scapular movement measurement in two groups of females with and without general hypermobility syndrome. upward rotation, s...

background: according to clinical observations, foot hyperpronation is very prevalent and may cause malalignment of the lower extremity, leading to structural and functional deficits in standing and walking. this study aimed at investigating the effect of foot hyperpronation on spine alignment in the standing position.   methods: thirty-five healthy males with an age range of 18-30 years partic...

Various recognition methodologies address to recognize and understand varieties of human activities. However, motion self-occlusion due to motion overlapping in the same region is a daunting task to solve. Various motion-recognition methods either bypass this problem or solve this problem in complex manner. Appearance-based template matching paradigms are simpler and hence these approaches fast...

A new method is described for interpreting image flow (or optical flow) in a small field of view produced by a rigidly moving curved surface. The equations relating the shape and motion of the surface to the image flow are formulated. These equations are solved to obtain explicit analytic expressions for the motion, orientation and curvatures of the surface in terms of the spatial derivatives (...

The stereoscopic three-dimensional (3D) display provides a 3D image by inducing binocular disparity for the observers who wear special glasses. With the rapid progress in flat panel display technologies, the stereoscopic 3D display is becoming a new benefit-model of the current display industry, and several kinds of commercial stereoscopic 3D products have been released and are attracting peopl...

The problem of real time in motion human identification based on face recognition has attracted the attention of the scientists and researchers. Because of real time face recognition in non-cooperative environments is a complex task, more tools and algorithms are needed in order to reduce the processing time required for a complete system to operate in an appropriate way. In this paper is prese...

Typically, image motion analysis in the frequency domain is performed according to the Motion From Fourier Coeecients, or MFFC principle. However , this principle excludes a class of motion that does not generate power spectra containing the origin of the frequency domain, which is usually referred to as Non-Fourier motion. This type of motion includes phenomena relevant to motion analysis such...

The compensation of cell motion is an important step in single-particle tracking analysis of live cells. This step is required in most of the cases, since the movement of subcellular foci is superimposed by the movement and deformation of the cell, while only the local motion of the foci is important to be analysed. The cell motion and deformation compensation is usually performed by means of i...

A vision system has been developed that recognizes and tracks multiple vehicles from sequences of gray-scale images taken from a moving car in hard real time. Recognition is accomplished by combining the analysis of single image frames with the analysis of the motion information provided by multiple consecutive image frames. In single image frames, cars are recognized by matching deformable gra...
