Inter-trial Gait Variability Reduction Using Continous Curve Registration
Timing in peak gait values shifts slightly between gait trials. When gait data are averaged, some of the standard deviation can be associated to this inter-trial variability unless normalization is carried out beforehand. The objective of this study was to determine how continuous curve registration, an alignment technique, can reduce inter-subject variability in gait data without altering the ...
متن کاملA visual tracking algorithm by integrating rigid model and snakes
This paper presents a robust vision algorithm for tracking the boundary of an object with an arbitrary shape by using monocular image sequences. This method consists of a curve registration based optimization technique and a deformable contour model (”snakes”) for the global and the local motion estimations, respectively. By combining techniques, we overcome, among other problems, inaccurate es...
متن کاملReduction of gait data variability using curve registration.
Timing in peak gait values shifts slightly between gait trials. When averaged, the standard deviation (S.D.) in gait data may increase due to this inter-trial variability unless normalization is carried out beforehand. The objective of this study was to determine how curve registration, an alignment technique, can reduce inter-subject variability in gait data without perturbing the curve charac...
متن کاملIndirect illumination on curve surfaces
In this paper we suggest improved method of photon registration on curve surfaces, presented by triangulated mesh with “true” normals in mesh vertices. Such presentation is widely used for simulation the differing effects of light and color across the surface of an object (Phong shading). It was found that direct photon registration, which does not take into account interpolated (smooth) normal...
متن کامل3D Registration of Curves and Surfaces using Local Differential Information
This article presents for the first time a global method for registering 3D curves with 3D surfaces without requiring an initialization. The algorithm works with 2-tuples point+vector that consist in pairs of points augmented with the information of their tangents or normals. A closed-form solution for determining the alignment transformation from a pair of matching 2-tuples is proposed. In add...
