1. Measuring Organelle Shape in 3D in Stem Cells Cultured on Nanofiber Scaffolds
Carl George Simon Jr, Peter Bajcsy, Wojtek J Tutak, Jyotsnendu (Jyotsnendu) Giri
Previous work has demonstrated that culture of osteoprogenitor cells on nanofiber scaffolds can
potentiate osteogenic differentiation [1-4]. Culture of cells in nanofiber scaffolds causes changes
to cell morphology, suggesting that morphological ...
2. Calibrating multiple microscopes with a smartphone
Peter Bajcsy, Mary C Brady, Jacob Siegel
Summary: The iPhone liquid crystal displays allows efficient and accurate calibration of an inexpensive array of handheld microscopes for measuring microscopic dynamic events over a large field of view.
How does one build an inexpensive array of ha ...
3. Re-projection of Terabyte-Sized Images
Peter Bajcsy, Antoine Vandecreme, Mary C Brady
This work addresses the problem of re-projecting a terabyte-sized 3D data set represented as a set of 2D Deep Zoom pyramids. In general, a re-projection for small 3D data sets is executed directly in RAM. However, RAM becomes a limiting factor for te ...
4. Terabyte Size Image Computations on Hadoop Cluster Platforms
Peter Bajcsy, Antoine Vandecreme, Julien Marc Amelot, Phuong Thi Thu Nguyen, Joe Chalfoun, Mary C Brady
We present a characterization of four basic terabyte size image computations on a Hadoop cluster in terms of their relative efficiency according to the modified Amdahl‰s law. The work is motivated by the fact that there is a lack of standard benchmar ...
5. Understanding impact of image quality on segmentation accuracy
YaShian Li-Baboud, Antonio Cardone, Joe Chalfoun, Peter Bajcsy, John T Elliott
We introduce a methodology for microscopy settings assessment and segmentation accuracy prediction based on image quality descriptors.
6. Segmenting Time-lapse Phase Contrast Images of Adjacent NIH 3T3 Cells
Joe Chalfoun, Alden A Dima, Marcin Kociolek, Michael W Halter, Antonio Cardone, Adele P Peskin, Peter Bajcsy, Mary C Brady
We present a new method for segmenting phase contrast images of NIH 3T3 fibroblast cells that is accurate even when cells are in contact. The problem of segmentation, when cells are in contact, poses a challenge to the accurate automation of cell cou ...
7. Versus: A Framework for General Content-Based Comparisons
Peter Bajcsy, Antoine Vandecreme, Benjamin J Long, Paul Khouri Saba, Joe Chalfoun, Luigi Marini, Rob Kooper, Michal Ondrejcek, Kenton McHenry, Smruti Padhy
Versus is a framework for the execution and dissemination of customizable content-based file comparison methods. Given digital objects such as files, database entries, or in-memory data structures, we are interested in establishing their proximity (i ...
8. Data Quality for High Content Screening
YaShian Li-Baboud, Oleg Aulov, Peter Bajcsy
TO HAVE CONFIDENCE IN THE KNOWLEDGE GLEANED FROM DATA, IT IS ESSENTIAL TO VERIFY THE QUALITY OF THE DATA
SOURCES AND TO HAVE A MEANS OF QUANTIFYING THE POTENTIAL UNCERTAINTIES DUE TO THE QUALITY OF DATA FOR MAKING
CRITICAL, INTELLIGENT DECISIONS. ...
9. Conformance of Image Features to Classifier Assumptions
Julien Marc Amelot, Peter Bajcsy, Mary C Brady
Cell measurements are derived frequently from the results of pixel classification and contiguous
region segmentation of microscopy images. Image segmentation is accomplished by classifying image
pixels based on high dimensional image features com ...
10. Web Accessible Image Similarity Measurements
Antoine Vandecreme, Paul Khouri Saba, Benjamin J Long, Joe Chalfoun, Peter Bajcsy, Mary C Brady
