Rüfenacht D, Fredembach C, Süsstrunk S.
PMID: 26353346
IEEE Trans Pattern Anal Mach Intell. 2014 Aug;36(8):1672-8. doi: 10.1109/TPAMI.2013.229.

We present a method to automatically detect shadows in a fast and accurate manner by taking advantage of the inherent sensitivity of digital camera sensors to the near-infrared (NIR) part of the spectrum. Dark objects, which confound many shadow...

Rüfenacht A, Boschetti A.
PMID: 16228435
Photosynth Res. 2000;63(3):249-58. doi: 10.1023/A:1006472325830.

The majority of the proteins in the chloroplast are encoded in the nucleus and synthesised in the cytoplasm as precursors with N-terminal extensions. These targeting sequences guide the precursor proteins into the chloroplast where they are immediately cleaved off...

OBJECTIVE: The importance of hemodynamics in the etiopathogenesis of intracranial aneurysms (IAs) is widely accepted. Computational fluid dynamics (CFD) is being used increasingly for hemodynamic predictions. However, alogn with the continuing development and validation of these tools, it is...

An in vitro study to define the term "dense packing" of aneurysms with detachable coils, liquid embolic material and their combination.

Interventional neuroradiology : journal of peritherapeutic neuroradiology, surgical procedures and related neurosciences

SUMMARY: The purpose of this study was to define the terms minimal and maximal "dense packing" of a given cavity with platinum coils and liquid material (cellulose acetate polymer; CAP) using precise in vitro volumetric methods. Tests were performed...

Base-Anchored Model for Highly Scalable and Accessible Compression of Multiview Imagery.

IEEE transactions on image processing : a publication of the IEEE Signal Processing Society

Ruefenacht D, Naman AT, Mathew R, Taubman D.
PMID: 30676962

We present a compression scheme for multiview imagery that facilitates high scalability and accessibility of the compressed content. Our scheme relies upon constructing at a single base view, a disparity model for a group of views, and then utilizing...

The effects of aortic coarctation on cerebral hemodynamics and its importance in the etiopathogenesis of intracranial aneurysms.

Journal of vascular and interventional neurology
