Complete system for head tracking using motion-based particle filter and randomly perturbed active contour
- in Proceedings oj SPIE,Image and Video Communications and Processing, March 2005
"... Many real world applications in computer and multimedia such as augmented reality and environmental imaging require an elastic accurate contour around a tracked object. In the first part of the paper we introduce a novel tracking algorithm that combines a motion estimation technique with the Bayesia ..."

with the Bayesian Importance Sampling framework. We use Adaptive Block Matching (ABM) as the motion estimation technique. We construct the proposal density from the estimated motion vector. The resulting algorithm requires a small number of particles for efficient tracking. The tracking is adaptive to different
State estimation in hybrid systems with a bounded number of mode transitions
- in Proc. Fusion 2010, 13th International Conference on Information Fusion
, 2010
"... Abstract – We consider the problem of tracking the state of a hybrid system capable of performing a bounded number of mode switches. The system is assumed to follow either a nominal or an anomalous model, where the nominal model may stand for, e.g., the non-maneuvering motion regime of a target or t ..."

based on the above error function. This hybrid learning controller combines the features of an indirect and a direct adaptive learning control such that the tradeoff between plant knowledge and control knowledge can be realized by adjusting a weighting factor. As in general the nonlinearities
Proceedings of the World Congress on Nature and Biologically Inspired Computing (NaBIC2010) An Adaptive Mutation Operator for Artificial Immune Network Using Learning Automata in Dynamic Environments
"... Abstract—Many real world problems are mostly time varying optimization problems, which require special mechanisms for detection changes in environment and then response to them. This paper proposes a hybrid optimization method based on learning automata and artificial immune network for dynamic envi ..."

DOI 10.1007/s00138-008-0130-6 ORIGINAL PAPER Real-time gaze tracking with appearance-based models
"... Abstract Psychological evidence has emphasized the importance of eye gaze analysis in human computer inter-action and emotion interpretation. To this end, current image analysis algorithms take into consideration eye-lid and iris motion detection using colour information and edge detec-tors. However ..."

Iterative Learning Air-Fuel Ratio Control with Adaptation in Spark Ignition Engines
"... Abstract-The paper addresses the problem of air-fuel ratio (AFR) stabilization applying learning techniques. The proposed strategy consists in iterative redesign of control coefficients based on the control obtained in a previous step in conjunction with an adaptive scheme. The interesting feature ..."

Vision-aided Inertial Navigation for Resource-constrained Systems
"... Abstract — In this paper we present a resource-adaptive framework for real-time vision-aided inertial navigation. Specifically, we focus on the problem of visual-inertial odometry (VIO), in which the objective is to track the motion of a mobile platform in an unknown environment. Our primary interes ..."
