2013 Proceedings of the 25th ICME conference francophone on l'Interaction Homme-Machine - IHM '13  
Results indicate that relative pointing in the frame of the physical object is less error prone and is less subject to registration jitter than screencentered crosshair pointing.  ...  It is therefore important to study the impact of registration jitter on interaction and in particular on pointing at augmented objects where precision may be required.  ...  ACKNOWLEDGEMENTS Special thanks to the students who participated in the experiment.

Quantitative reconstruction of time-varying 3D cell forces with traction force optical coherence microscopy [article]

Jeffrey A Mulligan, Xinzeng Feng, Steven G Adie
2018 bioRxiv   pre-print
Due to the reliance of TF-OCM on computational imaging methods, we have provided extensive discussion of the underlying equations, assumptions, and failure modes of these methods.  ...  We applied TF-OCM to quantify CTFs exerted by isolated NIH-3T3 fibroblasts embedded in Matrigel, with five-minute temporal sampling, using images which spanned a 500x500x500 μm3 field-of-view.  ...  High concentrations of beads allow for substrate deformations to be sampled more densely in 293 space, and therefore can help to mitigate the impact of error/measurement noise.  ...

Deep Feature based Cross-slide Registration [article]

Ruqayya Awan, Shan E Ahmed Raza, Johannes Lotz, Nick Weiss, Nasir Rajpoot
2022 arXiv   pre-print
We compared the performance of data-driven features with that of hand-crafted features on the COMET dataset. Our approach can align the images with low registration errors.  ...  Generally, the success of non-rigid registration is dependent on the quality of rigid registration.  ...  Overall registration error for T is computed by either taking mean or median of the aggregated rTRE, namely as the median of median rTRE (MMrTRE) and the average of median rTRE (AMrTRE).  ...
