Steerable Filters for Orientation Estimation and Localization of Fluorescent Dipoles

Michaël Unser, Theo Lasser, François Aguet

Fluorescence localization microscopy (i.e., PALM, STORM) has enabled optical imaging at nanometer-scale resolutions. The localization algorithms used in these techniques rely on fitting a 2-D Gaussian to the in-focus image of individual fluorophores. For ...

Diffusion strategies for distributed Kalman filtering: formulation and performance analysis

Ali H. Sayed

We consider the problem of distributed Kalman filtering, where a set of nodes are required to collectively estimate the state of a linear dynamic system from their individual measurements. Our focus is on diffusion strategies, where nodes communicate with ...

Real-time estimation of vehicle-count within signalized links

The number of vehicles included in a metered motorway ramp or an urban signalized link at any time is valuable information for real-time control. A Kalman-Filter is employed to produce reliable estimates of this quantity based on real-time measurements of ...

Multi-camera 3d person tracking with particle filter in a surveillance environment

Jean-Marc Odobez

In this work we present and evaluate a novel 3D approach to track single people in surveillance scenarios, using multiple cameras. The problem is formulated in a Bayesian filtering framework, and solved through sampling approximations (i.e. using a particl ...

GPS/INS Integrity in Airborne Mapping

Jan Skaloud, Yannick Stebler

The quality of the laser point cloud georeferencing in airborne laser scanning missions is largely related to the quality of the GPS solution. The latter is obtained by post- processing the differential carrier-phase measurements in order to reach the requ ...

Eléments d'acoustique générale

Vincent Martin

Ce manuel d’enseignement présente les principaux éléments de l’acoustique physique. Une approche didactique a été privilégiée, les thèmes présentés étant abordés par le biais d’une description d’objets courants extraits par exemple de la lutherie, de l’env ...

Refining preference-based search results through Bayesian filtering

Pearl Pu Faltings, Jiyong Zhang

Preference-based search (PBS) is a popular approach for helping consumers find their desired items from online catalogs. Currently most PBS tools generate search results by a certain set of criteria based on preferences elicited from the current user durin ...

Target tracking using a joint acoustic video system

Volkan Cevher

In this paper, we present a particle filter that exploits multi modal information for robust target tracking. We demonstrate a Bayesian framework for combining acoustic and video information using a state space approach. A proposal strategy for joint acous ...

Acoustic multi target tracking using direction-of-arrival batches

Volkan Cevher

In this paper, we propose a particle filter acoustic direction-of-arrival (DOA) tracker to track multiple maneuvering targets using a state space approach. The particle filter determines its state vector using a batch of DOA estimates. The filter likelihoo ...

Mixed-mode implementation of particle filters

Volkan Cevher

In this paper, we develop new mixed-mode implementations for particle filters and compare them to a digital implementation. The motivation for the mixed-mode implementation is to achieve low-power implementation of particle filters. The specific applicatio ...
