Robust Jacobian Estimation for Uncalibrated Visual Servoing

• Azad Shademan, Amir Massoud Farahmand, Martin Jägersand
• 2010 IEEE International Conference on Robotics…
• 2010

This paper addresses robust estimation of the uncalibrated visual-motor Jacobian for an image-based visual servoing (IBVS) system. The proposed method does not require knowledge of model or system… (More)

Experimental evaluation of contact-less hand tracking systems for tele-operation of surgical tasks

• Yonjae Kim, Peter C. W. Kim, Rebecca Selle, Azad Shademan, Axel Krieger
• 2014 IEEE International Conference on Robotics…
• 2014

This paper reports an evaluation of contact-less hand tracking sensors for the use of tele-operation, in particular for surgical robotics applications. Two hand tracking systems are investigated:… (More)

Sensitivity analysis of EKF and iterated EKF pose estimation for position-based visual servoing

• Azad Shademan, Farrokh Janabi-Sharifi
• Proceedings of 2005 IEEE Conference on Control…
• 2005

Robust and real-time relative pose estimation is an integral part of a position-based visual servoing (PBVS) system. Traditionally, extended Kalman filter (EKF) has been used to solve for the… (More)

Towards Learning Robotic Reaching and Pointing: An Uncalibrated Visual Servoing Approach

• Azad Shademan, Amir Massoud Farahmand, Martin Jägersand
• 2009 Canadian Conference on Computer and Robot…
• 2009

It is desirable for a robot to be able to operate in unstructured environments. In this paper, we demonstrate how a robot can learn primitive skills and we show how to augment them. We formalize… (More)

Kinect technology for hand tracking control of surgical robots: technical and surgical skill comparison to current robotic masters

• Yonjae Kim, Simon Léonard, Azad Shademan, Axel Krieger, Peter C. W. Kim
• Surgical Endoscopy
• 2013

Current surgical robots are controlled by a mechanical master located away from the patient, tracking surgeon’s hands by wire and pulleys or mechanical linkage. Contactless hand tracking for surgical… (More)

Global Visual-Motor Estimation for Uncalibrated Visual Servoing

• Amir Massoud Farahmand, Azad Shademan, Martin Jägersand
• 2007 IEEE/RSJ International Conference on…
• 2007

In this paper, we present two methods for the estimation of a globally valid visual-motor model of a robotic manipulator. In conventional uncalibrated visual servoing, the visuo-motor function is… (More)

SEPO: Selecting by pointing as an intuitive human-robot command interface

• Camilo Perez Quintero, Romeo Tatsambon Fomena, Azad Shademan, Nina Wolleb, Travis Dick, Martin Jägersand
• 2013 IEEE International Conference on Robotics…
• 2013

Pointing to indicate direction or position is one of the intuitive communication mechanisms used by humans in all life stages. Our aim is to develop a natural human-robot command interface using… (More)

Clustering of singular value decomposition of image data with applications to texture classification

Model-based and Model-free Reinforcement Learning for Visual Servoing

• Amir Massoud Farahmand, Azad Shademan, Martin Jägersand, Csaba Szepesvári
• 2009 IEEE International Conference on Robotics…
• 2009

To address the difficulty of designing a controller for complex visual-servoing tasks, two learning-based uncalibrated approaches are introduced. The first method starts by building an estimated… (More)

Realtime Registration-Based Tracking via Approximate Nearest Neighbour Search

• Travis Dick, Camilo Perez Quintero, Martin Jägersand, Azad Shademan
• Robotics: Science and Systems
• 2013

We introduce a new 2D visual tracking algorithm that utilizes an approximate nearest neighbour search to estimate per-frame state updates. We experimentally demonstrate that the new algorithm capable… (More)
