abstract   bibtex   
Although visual feedback has enabled a wide range of robotic capabilities such as autonomous navigation and robotic surgery, low sampling rate and time delays of visual outputs con- tinue to hinder real-time applications. When partial knowledge of the target dynamics are available, however, we show the poten- tial of significant performance gain in vision-based target follow- ing. Specifically, we propose a new framework with Kalman fil- ters and multirate model-based prediction (1) to reconstruct fast- sampled 3D target position and velocity data, and (2) to com- pensate the time delay for general robotic motion profiles. The proposed framework substantially extend the capability of con- ventional visual servo methods that apply only to static or slowly moving target. Along the path, we study the impact of model- ing choices and the delay duration, build simulation tools, and experimentally verify different algorithms with a robot manipu- lator equipped with an eye-in-hand camera.

	Annote = {Thank you. The revised paper is attached. For the journal versions, I will consider:
Repetitive model in KF.
Test and analysis the effect of delays, see how delays impact other signal models.
Test other trajectory types.
IIR based MMP.
Maybe add adaptive estimation techniques. That is, the motion type will change during the following task.
Add more details of KF.
Update the experiment setup figure to include the robot controller and the desk computer.
Add figures to show the target trajectory in the image, 
My next priority will be the TIE paper rebuttal. At the meantime, I will do tests and discuss with you about the extensions for target tracking paper.
