This paper presents a method for the detection of objects that move independently of the observer in a 3D dynamic scene. Independent motion detection is achieved through processing of stereoscopic image sequences acquired by a binocular, rigidly moving observer. A weak assumption is made about the observer's motion (egomotion), namely that the direction of the translational and rotational compo...

This paper deals with state estimation of micro tunable capacitor subjected to nonlinear electrostatic force. For this end a nonlinear observer has been designed for state estimation of the structure.  Necessary and sufficient conditions for construction of the observer are presented. Stability of the observer is checked using Lyapunov theorem. Observer design is based on converting of differen...

This study investigates the interobserver and intraobserver reliability of qualitative behavior assessments (QBA) of individual pigs by 3 observer groups selected for their diverging backgrounds, experience, and views of pigs. Qualitative behavior assessment is a "whole animal" assessment approach that characterizes the demeanor of an animal as an expressive body language, using descriptors suc...

In this paper, we present a car tracking system which provides quantitative and qualitative motion estimates of the tracked car simultaneously from a moving observer. First, we construct three motion models (constant velocity, constant acceleration, and turning) to describe the qualitative motion of a moving car. Then the models are incorporated into the Extended Kalman Filters to perform quant...

Abstract. Tracking vehicles in image sequences of innercity road traffic scenes must be considered still to constitute a challenging task. Even if a-priori knowledge about the 3D shape of vehicles, of the background structure, and about vehicle motion is provided, (partial) occlusion and dense vehicle queues easily can cause initialization and tracking failures. A stepwise improvement of the tr...

accurate interpretation of radiographic images is dependent on viewing conditions. recently the number of radiology departments has been increased so it needs to use a workstation for reporting. the aim of this study was assess monitor performance and the effect of viewing conditions on object detection. this investigation aimed to quantify the effects of changes in box brightness and ambient l...

This chapter is intended as a resource for qualitative analysis of corpora of texts in human and social sciences. We will concentrate on the computerized analysis of text corpora 1 by obscuring the tools to analyze documents that are not strictly textual. These can, for example, be objects confided by informants, memories that the observer retains from his/her contact with the field or recordin...
