DOI: 10.1007/s12555-018-0199-2
Abstract: In this paper, we present a patch-based direct visual odometry (DVO) that is robust to illumination changes at a sequence of stereo images. Illumination change violates the photo-consistency assumption and degrades the performance of DVO,… read more here.

DOI: 10.1109/tmech.2019.2898509
Abstract: This paper focuses on the design of a 6 degrees of freedom visual servoing control law. Instead of using geometric visual features in standard vision-based approaches, the proposed controller makes use of wavelet coefficients as… read more here.

DOI: 10.1177/1756287216679946
Abstract: Background: Urethroplasty is often successful for the treatment of male urethral stricture disease, but limited data exists on recurrence management. Our goal was to evaluate direct visual internal urethrotomy (DVIU) as a treatment option for… read more here.
