An Algorithm for the Least Square-Fitting of Ellipses
Found in: Tools with Artificial Intelligence, IEEE International Conference on
By Nicola Greggio, Alexandre Bernardino, Cecilia Laschi, Paolo Dario, José Santos-Victor
Issue Date:October 2010
pp. 351-353
In this paper we propose a new algorithm for the least square fitting of ellipses from scattered data. Originally based on the one proposed by Fitzgibbon et Al in 1999, our procedure is able to overcome the numerical instability of that algorithm. We test ...
 
Unsupervised Greedy Learning of Finite Mixture Models
Found in: Tools with Artificial Intelligence, IEEE International Conference on
By Nicola Greggio, Alexandre Bernardino, Cecilia Laschi, Paolo Dario, José Santos-Victor
Issue Date:October 2010
pp. 219-224
This work deals with a new technique for the estimation of the parameters and number of components in a finite mixture model. The learning procedure is performed by means of a expectation maximization (EM) methodology. The key feature of our approach is re...
 
Microfabricated Instruments for Fetal Cardiac Surgery: Experiments on Haptic Tissue Recognition
Found in: Haptic Interfaces for Virtual Environment and Teleoperator Systems, International Symposium on
By Anna Eisinberg, Oliver Tonet, Paolo Dario, Giovanna Macri, Maria Chiara Carrozza
Issue Date:March 2006
pp. 39
This paper describes the performance of a microfabricated gripper, equipped with semiconductor strain gauges as force sensors, and teleoperated via a PHANTOM haptic interface. The main objective is to demonstrate that the force sensed by the gripper, when ...
