1. Calibrating multiple microscopes with a smartphone
Published: 4/1/2014
Authors: Peter Bajcsy, Mary C Brady, Jacob Siegel
Abstract: 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 ...

2. Depicting Web Images for the Blind and Visually Impaired
Published: 12/9/2013
Authors: Andrea Bajcsy, YaShian Li-Baboud, Mary C Brady
Abstract: A prototype to translate web graph and map images into 3D printed models in order to give the blind and visually impaired access to voting and election information.

3. Ontology for Big Systems: The Ontology Summit 2012 Communique
Published: 10/16/2013
Authors: Ram D Sriram, Mary C Brady
Abstract: The Ontology Summit 2012 explored the current and potential uses of ontology, its methods and paradigms, in big systems and big data: How ontology can be used to design, develop, and operate such systems. The systems addressed were not just software ...

4. Re-projection of Terabyte-Sized Images
Published: 10/7/2013
Authors: Peter Bajcsy, Antoine Vandecreme, Mary C Brady
Abstract: 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 ...

5. Terabyte Size Image Computations on Hadoop Cluster Platforms
Published: 10/7/2013
Authors: Peter Bajcsy, Antoine Vandecreme, Julien Marc Amelot, Phuong Thi Thu Nguyen, Joe Chalfoun, Mary C Brady
Abstract: 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 ...

6. Parallel Geometric Classification of Stem Cells by Their 3D Morphology
Published: 7/1/2013
Authors: Derek Juba, Antonio Cardone, Cheuk Yiu Ip, Carl George Simon Jr, Christopher K. Tison, Girish Kumar, Mary C Brady
Abstract: Autologous stem cells show great promise for tissue engineering as they can regenerate diseased or damaged tissue, without requiring an organ donor or causing immune rejection. A primary goal of regenerative medicine is to identify methods for contr ...

7. A Hybrid CPU-GPU System for Fourier-Based Stitching of Optical Microscopy Images
Published: 3/15/2013
Authors: Walid Keyrouz, Bertrand Clement Stivalet, Timothy J Blattner, Shujia Zhou, Joe Chalfoun, Mary C Brady
Abstract: We present a high performance hybrid CPU-GPU implementation that accelerates the Fourier-based stitching of 2D optical microscopy images to less than 1-minute (end-to-end execution times). This implementation takes advantage of coarse-grained parall ...

8. A Hybrid CPU-GPU Approach to Fourier-Based Image Stitching of Optical Microscopy Images
Published: 3/3/2013
Authors: Walid Keyrouz, Timothy J Blattner, Bertrand Clement Stivalet, Joe Chalfoun, Mary C Brady, Shujia Zhou
Abstract: We present a hybrid CPU-GPU approach for the Fourier-based stitching of optical microscopy images. This system achieves sub-minute stitching rates with large grids; it stitches a grid of 59x42 tiles in 26 seconds on a two-CPU (8 physical cores) & two ...

9. Segmenting Time-lapse Phase Contrast Images of Adjacent NIH 3T3 Cells
Published: 1/15/2013
Authors: Joe Chalfoun, Alden A Dima, Marcin Kociolek, Michael W Halter, Antonio Cardone, Adele P Peskin, Peter Bajcsy, Mary C Brady
Abstract: 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 ...
