In this paper, a moving object detection method in video sequences is described. In the 3rst step, the camera motion is eliminated using motion compensation. An adaptive subband decomposition structure is then used to analyze the motion compensated image. In the “low–high” and “high–low” subimages moving objects appear as outliers and they are detected using a statistical detection test based o...

A curvature compensation technique for bandgap voltage references that utilizes an adaptive reference temperature is presented. This compensation technique is intended for high-resolution temperature-stable analogdigital converters. A test circuit had been designed in a 0.6 μm CMOS technology to implement this technique. The reference voltage has a simulated temperature coefficient of 2.3 ppm/ ...

In the paper, we introduce the concepts of dynamic object identification and verification using video. A generalized Hausdorff metric, which is more robust to noise and allows a confidence interpretation, is suggested for the identification and verification problem. Parameters from sensor motion compensation procedure are incorporated into the search step such that the Hausdorff metric based ma...

Abstract. We consider a manager, who allocates some fixed total payment amount between N rational agents in order to maximize the aggregate production. The profit of i-th agent is the difference between the compensation (reward) obtained from the manager and the production cost. We compare (i) the normative compensation scheme, where the manager enforces the agents to follow an optimal cooperat...

The Performance-Potential-Metamodel PerPot describes the dynamics of load performance interaction by means of delayed flows between potentials. The basic idea is that of antagonism: The load input in the same way feeds a strain potential as well as a response potential, which then decrease respectively increase the performance potential by delayed flows. These delays play an important role in c...

We examine the performance of 84 firms that adopt value-based management (VBM) systems during the period 1984-1997. The typical firm significantly improves matched-firm-adjusted residual income after adopting VBM. This improvement persists for the five post-adoption years studied. After controlling for possible sample bias, we find that large firms show less improvement than small firms. We fin...

This paper is concerned with the detection and tracking of obstacles from a camera mounted on a vehicle with a view to driver assistance. To achieve this goal, we have designed a technique entirely based on image motion analysis. We perform the robust estimation of the dominant image motion assumed to be due to the camera motion. Then by considering the outliers to the estimated dominant motion...

In this paper, we propose an Error Concealment algorithm for INTRA-frame losses over packet loss channels. The novelty is that not only the INTRA-frame but also the subsequent INTER-frames are error concealed. We use the received INTRA-MBs to refine their neighbors based on the strong correlation between adjacent pixel values. In addition, Motion Compensation is used to reconstruct the INTER-pi...

The aim of this work is to reconstruct clean speech solely from a stream of noise-contaminated MFCC vectors, as may be encountered in distributed speech recognition systems. Speech reconstruction is performed using the ETSI Aurora back-end speech reconstruction standard which requires MFCC vectors, fundamental frequency and voicing information. In this work, fundamental frequency and voicing ar...
