Optimization based control for target estimation and tracking via highly observable trajectories

Colin Neil Jones, Andrea Alessandretti, António Pedro Rodrigues de Aguiar

This paper presents a Model Predictive Control (MPC) scheme to solve the target estimation and tracking problem. The objective is to derive a feedback law that drives a follower vehicle to a target vehicle using on-line estimation of the target position an ...

Robust visual tracking using feature selection

Fabien Willemin

Visual tracking has become a very important component in computer vision, but achieving a robust, reliable and real time tracking remains a real challenge.In order to improve the actual state-of-the-art, we choose to study and improve one of the most perfo ...

Reconfigurable Forward Homography Estimation System for Real-Time Applications

Yusuf Leblebici, Vladan Popovic

Image processing and computer vision algorithms extensively use projections, such as homography, as one of the processing steps. Systems for homography calculation usually observe homography as an inverse problem and provide an exact solution. However, the ...

High-throughput analysis of the morphology and mechanics of tip growing cells using a microrobotic platform

Mahmut Selman Sakar, Dimitrios Felekis, Geraldo Mecja

We present a microrobotic platform that combines MEMS-based capacitive force sensing technology, a dual-stage positioning system and a real-time control and acquisition architecture with computer vision automation to manipulate and mechanically characteriz ...

3D high-density localization microscopy using hybrid astigmatic/biplane imaging and sparse image reconstruction

Michaël Unser, Suliana Manley, Seamus John Holden, Lina Carlini

Localization microscopy achieves nanoscale spatial resolution by iterative localization of sparsely activated molecules, which generally leads to a long acquisition time. By implementing advanced algorithms to treat overlapping point spread functions (PSFs ...

Multi-camera face detection and recognition applied to people tracking

Michail Zervos

This thesis describes the design and implementation of a framework that can track and identify multiple people in a crowded scene captured by multiple cameras. A people detector is initially employed to estimate the position of individuals. Those positions ...

"Self pop-out": agency enhances self-recognition in visual search

Olaf Blanke, Roy Salomon, Oliver Alan Kannape, Joan Llobera Mahy, Mei Ling Melanie Lim

In real-life situations, we are often required to recognize our own movements among movements originating from other people. In social situations, these movements are often correlated (for example, when dancing or walking with others) adding considerable d ...

Online Modeling For Realtime Facial Animation

Mark Pauly, Sofien Bouaziz

We present a new algorithm for realtime face tracking on commodity RGB-D sensing devices. Our method requires no user-specific training or calibration, or any other form of manual assistance, thus enabling a range of new applications in performance-based f ...

Effectiveness of different sensing modalities in predicting targets of reaching movements

Human motion recognition is essential for many biomedical applications, but few studies compare the abilities of multiple sensing modalities. This paper thus evaluates the effectiveness of different modalities when predicting targets of human reaching move ...
