Computer Vision and Pattern Recognition

Crowd Behavior Characterization for Scene Tracking

In this work, we perform an in-depth analysis of the specific difficulties a crowded scene dataset raises for tracking algorithms. Starting from the standard characteristics depicting the crowd and their limitations, we introduce six en-tropy…

Performance bound for robust array calibration in radio interferometry

Robust calibration of next-generation radio-interferometers, as the square kilometer array (SKA) for instance, is a crucial prepro-cessing step for sky imaging. Recently, several robust calibration es-timators based on the use of well known strong…

Wide baseline pose estimation from video with a density-based uncertainty model

Robust wide baseline pose estimation is an essential step in the deployment of smart camera networks. In this work, we highlight some current limitations of conventional strategies for relative pose estimation in difficult urban scenes. Then, we…

Integrating Visual and Geometric Consistency for Pose Estimation

In this work, we tackle the problem of estimating the relative pose between two cameras in urban environments in the presence of additional information provided by low quality localization and orientation sensors. An M-estimator based approach…

A new DC-DC piezoelectric Converter

In this paper a new topology of step down DC-DC converter using a piezoelectric component as storage element is presented. DC-DC conversion process is based on electrical-mechanical-electrical transducer with Zero Voltage Switching (ZVS) for…

DC-DC converter with GaN transistor and coupled with monolithic ICT sintered by PECS/SPS

This paper presents an implementation of the voltage regulator module (VRM) DC-DC converter operating at 2 MHz using 3 interleaved switching cells whose outputs are magnetically coupled by monolithic intercell transformers (ICT). The innovation…
