The Stepping Distance Transformation
نویسنده
چکیده
An algorithm Mscan is proposed for the computation of the distance transform of a feature in an image with respect to a chamfer distance. The algorithm is na vely simple and can therefore be easily parallellized. It seems to be new, even for special cases. It is not correct for arbitrary chamfer distances but, by a general analysis of masks and their weights, suucient conditions for its correctness are obtained. If the image is rectangular with edges parallel to the coordinate axes, all chamfer distances used to approximate the Euclidean distance satisfy these conditions.

The characteristics of multi-directional step distance and the association between stepping laterality and walking ability of patients with stroke
[Purpose] The purpose of this study was to determine the effect of stepping limb and step direction on step distance and the association of step distance and stepping laterality in step difference with walking ability and motor dysfunction. [Subjects and Methods] The subjects were thirty-nine patients with chronic hemiparesis as a result of stroke, who performed the MSL (Maximum Step Length) te...
متن کاملPerception of maximum stepping and leaping distance: Stepping affordances as a special case of leaping affordances.
Successfully performing everyday behaviors requires perceiving affordances-possibilities for behavior that depend on the fit between environmental properties and action capabilities. Whereas affordances for some behaviors are primarily constrained by relatively static geometric properties of the perceiver (non-launching behaviors such as stepping), others are additionally constrained by dynamic...
متن کاملA new approach based on state conversion to stability analysis and control design of switched nonlinear cascade systems
In this paper, the problems of control and stabilization of switched nonlinear cascade systems is investigated. The so called simultaneous domination limitation (SDL) is introduced in previous works to assure the existence of a common quadratic Lyapunov function (CQLF) for switched nonlinear cascade systems. According to this idea, if all subsystems of a switched system satisfy the SDL, a CQLF ...

متن کاملPHASE TRANSFORMATION DURING WEAR OF AISI STAINLESS STEEL 316
Abstract: Austenitic stainless steels exhibit a low hardness and weak tribological properties. The wear behaviour of austenitic stainless steel AISI 316 was evaluated through the pin on disc tribological method. For investigating the effect of wear on the changes in microstructure and resistance to wear, optical microscopy and scanning electron microscope were used. The hardness of the worn...
