This paper considers the problem of autonomous robot navigation in dynamic and congested environments. The predictive navigation paradigm is proposed where probabilistic planning is integrated with obstacle avoidance along with future motion prediction of humans and/or other obstacles. Predictive navigation is performed in a global manner with the use of a hierarchical Partially Observable Mark...

Fundamentals of Inertial Navigation, Satellite-based Positioning and their Integration is an introduction to the field of Integrated Navigation Systems. It serves as an It emphasizes that a survey of future inertial navigation concepts associated with the kalman filtering. He has been active in discussing the necessary details inertial navigator. Accuracy an introduction to the material. The pe...

Gallium arsenide (GaAs) based microaccelerometers are being developed for guidance and navigation subsystems, and various microsensor systems. The microaccelerometer is a microelectromechanical system (MEMS) micromachined on top of GaAs substrate or GaAs integrated cirwits. The MEMS accelerometer is integrated on the same chip as the GaAs readout circuit and the GaAs analog to digital converter...

With the explosive growth of the World Wide Web, browsers especially Netscape and Microsoft Internet Explorer have found their users increasing exponentially. Thus minor problems in these browsers affect millions of individuals. The stack based navigation structure of these browsers is one such example. We present the Unified navigation Architecture for Hypertext Applications (UNAHA), which not...

This paper introduces the basic concept of the Position Navigation and Timing (PNT) Module as future part of a ship side Integrated Navigation System (INS). Core of the PNT Module is a sensor fusion based processing system (PNT Unit). The paper will focus on important aspects and first results of the initial practical realization of such a PNT Unit, including a realization of a Consiste...

This article describes ongoing research in the use computer vision gesture and speech recognition techniques as a natural interface for video content navigation, and the design of a navigation and browsing system that caters to these natural means of computer-human interaction. For consumer applications, video content navigation presents two challenges: (1) how to parse and summarize multiple v...

Autonomous mobile entity navigation through dynamic and unknown environments is an essential part of many mission critical applications like search and rescue and fire fighting. The dynamism of the environment makes it particularly difficult to achieve navigation using just on-board sensors and existing navigation methods. This motivates the integration of wireless sensor networks with navigati...

This paper presents the MATISSE system: Mosaicking Advanced Technologies Integrated in a Single Software Environment. This system aims at producing in-line and off-line geo-referenced video mosaics of seabed given a video input and navigation data. It is based upon several techniques of image and signal processing which have been developed at Ifremer these last years in the fields of image mosa...
