The level of detail of an image can be expressed in terms of its topology, i.e. the distribution of Morse critical points and their types, which in turn is governed by resolution. We study the behaviour of critical points as a function of resolution for Gaussian scale-space images using catastrophe theory. Unlike existing literature, in which one employs local, so-called canonical coordinates f...

In this paper, a new model inverse optimal iterative learning control algorithm is practically implemented on an industrial gantry robot. The algorithm has only one tuning parameter which can be adjusted to provide a balance between convergence speed and robustness. Results show that the algorithm is capable of learning the required trajectory in very few iterations. However at this convergence...

Rotational and vibrational distributions for the exchange reaction H + H2->H2+ H are obtained numerically for reaction in a plane and compared with the vibrationally adiabatic solutions. Evidence is obtained regarding the two adiabatic solutions for the final rotational state predicted earlier and for. the disappearance of one of these at higher initial relative velocity. Good agreement between...

Llde, A., Trajectory generation from noisy positions of object features for teaching robot paths, Robotics and Autonomous Systems, 11 (1993) 113-127. In this paper we discuss a method for generating a trajectory describing robot path using a sequence of noisy positions of features belonging to a moving object obtained from a robot's sensor system. In order to accurately estimate this trajectory...

Locating 3-D rigid objects reliably from segmented range images in the presence of occlusion, noise, or discrepancies between image and model is important for many applications. While surface features work perfectly for matching, point and line features are still needed for locating. Fast, non-iterative locating methods usually require accurate point correspondences, and do not tolerate signifi...

I present a new set of tools for detection of intersections among tracks in 2-D Cartesian or geographic coordinates. These tools allow for evaluation of crossover errors at intersections, analysis of such crossover errors to determine appropriate linear models of systematic corrections for each track, and application of these corrections and further adjustments to data that completely eliminate...

The non-availability of ellipsoidal heights local geodetic Datums has made it necessary for the application transformation models to available global obtain their respective theoretical in Datums. It is required know accuracy, as well reliability any model interest before its application. For that reason, this study comparatively analyses Molodensky and Kotsakis between geocentric non-geocentri...

This study proposes the use of an innovative array of accelerometers for inertial tracking that is enabled through the use of a non-Cartesian hyper-coordinate frame. Traditional inertial tracking technologies employ an array of accelerometers and gyroscopes oriented in the orthogonal axes of the Cartesian coordinate system. The gyroscope sensors are responsible for deducing the relative orienta...

Ž . A direct transfer of Cartesian molecular force fields FF and electric property tensors is tested on model systems and compared to transfer in internal coordinates with an aim to improve simulation of vibrational spectra for larger molecules. This Cartesian transformation can be implemented easily and offers greater flexibility in practical computations. It can be also applied for transfer o...

Diverse evidence shows that perceptually integral dimensions, such as those composing color, are represented holistically. However, the nature of these holistic representations is poorly understood. Extant theories, such as those founded on multidimensional scaling or general recognition theory, model integral stimulus spaces using a Cartesian coordinate system, just as with spaces defined by s...
