THE ESTIMATION OF GEOMETRY AND MOTION OF A SURFACE FROM IMAGE SEQUENCES BY MEANS OF LINEARIZATION OF A PARAMETRIC MODEL

引用

computer VISION GRAPHICS AND IMAGE PROCESSING 1990年第1期50卷 1-28页

作者： KORSTEN, MJ HOUKES, Z Control Systems and Computer Engineering Laboratory Faculty of Electrical Engineering University of Twente P.O. Box 217 7500AE Enschede The Netherlands

A method is given to estimate the geometry and motion of a moving body surface from image sequences. To this aim a parametric model of the surface is used, in order to reformulate the problem to one of parameter estimation. After linearization of the model standard linear estimation methods can be used to estimate the parameters. The main contribution of this paper is that a method is provided to perform the linearization without specifying the model. Therefore structure from motion estimation and nonrigid body motion estimation can be performed regardless of the model.

Markets globalization makes industrial companies to change radically, becoming more flexible, customer oriented and ague in manufacturing. Consequently, the enterprise software applications are becoming more and more complex, exploiting distributed object technology in multi-tier architectures. The aim of the paper is to present the design specification for an enterprise application that integrates the ERP concept in three-tier architecture, containing modularized, distributed subsystems in configurable and maintainable software. Starting from the customer order, to planned order dispatch, the ERP main components and the information flow within the system is presented. Then, the software architecture is discussed, where the ERP components are implemented using Enterprise Java Beans (EJB), deployed in a J2EE application server, for performing transactions with business environment and the database. Constructing the visual model in Unified Modeling Language (UML), the application is designed and analyzed. The use case diagram of the system is presented. © 2005 IEEE.

This paper presents a self-organizing heuristic iterative algorithm for solving Travelling Salesman Problem. In the algorithm, firstly priority values of the edges are determined. Then, varied solutions are found. After that, the priority values of the edges are updated according to these solutions. Then, all the edges are sorted in descending order according to the priority values and in order to improve solutions an iterative algorithm is used. Greedy algorithm is used to find the solution in each iteration and the priority values of the edges are updated according to the solution. The proposed algorithm is compared with Nearest Neighbour and Greedy algorithm. Experimental results show that the proposed algorithm is efficient. © 2016

A SUFFICIENT CONDITION FOR OUTPUT-FEEDBACK STABILIZATION OF UNCERTAIN systems

A sufficient condition is derived for the existence of an output constant gain feedback controller which stabilizes a single-input single-output dynamical system with a linear nominal part and matched uncertainties. The sufficient condition is significantly less restrictive than a recently derived one [1]. If such a controller exists, it may readily be computed.

Differential balancing theory for nonlinear model reduction relies on differential controllability and observability functions. In this paper, we further investigate them from two different perspectives. First, we establish novel connections between these differential energy functions and their incremental counterparts by assuming the existence of the corresponding optimal state feedback for each controllability function. Specifically, an upper bound on the incremental controllability/observability function is provided by the corresponding differential energy function. Conversely, an upper bound on the differential controllability function can be estimated from the incremental controllability function. Furthermore, the differential observability function can be constructed from the incremental observability function. Second, we explore the positive definiteness of the differential controllability/observability function in the context of controllability/observability and stability. © 2025, CC BY-NC-ND.

The problem of signal processing is extracting the desired target speaker while suppressing the annoying background noise in complex recording situation, where exists third-party talker, transport vehicle or interference, noise. Speech quality or speech intelligibility are the major characteristics, which confirm the effectiveness of processed method. In speech applications, such as hearing-aids, hands-free telephony, teleconferencing, acoustic instruments, microphone array (MA) is applied for increasing the speech quality. MA uses the spatial response, the priori information about direction - of - arrival (DOA) of interest signal, the properties of recording environment to obtain speech components and remove noise. Generalized Sidelobe Canceller (GSC) is one of the most widely exploited in microphone array beamforming, due to its convenience and effective noise reduction. However, in several situations, the performance of GSC beamformer is often degraded, because of the imprecise DOA. In this paper, the authors suggested an additive spectral mask for improving the evaluation of GSC beamformer. The resulting experiment proves the received advantage of the author’s proposed algorithm to increase in the term of the signal-to-noise ratio (SNR). © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.

Communication-centric Integrated Sensing and Communication (ISAC) has been recognized as a promising methodology to implement wireless sensing functionality over existing network architectures, due to its cost-effectiveness and backward compatibility to legacy cellular systems. However, the inherent randomness of the communication signal may incur huge fluctuations in sensing capabilities, leading to unfavorable detection and estimation performance. To address this issue, we elaborate on random ISAC signal processing methods in this article, aiming at improving the sensing performance without unduly deteriorating the communication functionality. Specifically, we commence by discussing the fundamentals of sensing with random communication signals, including the performance metrics and optimal ranging waveforms. Building on these concepts, we then present a general framework for random ISAC signal transmission, followed by an in-depth exploration of time-domain pulse shaping, frequency-domain constellation shaping, and spatial-domain precoding methods. We provide a comprehensive overview of each of these topics, including models, results, and design guidelines. Finally, we conclude this article by identifying several promising research directions for random ISAC signal transmission. © 2025, CC BY-SA.
