11. Terabyte Size Image Computations on Hadoop Cluster Platforms
Peter Bajcsy, Antoine Vandecreme, Julien M. 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 ...
12. Parallel Geometric Classification of Stem Cells by Their 3D Morphology
Derek Juba, Antonio Cardone, Cheuk Yiu Ip, Carl George Simon Jr., Christopher K. Tison, Girish Kumar, Mary C Brady
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 ...
13. A Hybrid CPU-GPU System for Fourier-Based Stitching of Optical Microscopy Images
Walid Keyrouz, Bertrand Clement Stivalet, Timothy J Blattner, Shujia Zhou, Joe Chalfoun, Mary C Brady
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 ...
14. A Hybrid CPU-GPU Approach to Fourier-Based Image Stitching of Optical Microscopy Images
Walid Keyrouz, Timothy J Blattner, Bertrand Clement Stivalet, Joe Chalfoun, Mary C Brady, Shujia Zhou
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 ...
15. 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 ...
16. Big Data Issues in Quantitative Imaging
Mary C Brady, Alden A Dima, Charles D. Fenimore, James J Filliben, John Lu, Adele P Peskin, Mala Ramaiah, Ganesh Saiprasad, Ram D Sriram
17. Conformance of Image Features to Classifier Assumptions
Julien M. 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 ...
18. Monte Carlo and dynamics simulations of cdk5 Kinase inhibitor peptides p5 in aqueous solution
Antonio Cardone, Sergio Hassan, Mary C Brady, Ram D Sriram, Harish C. Pant
Protein function depends on shape changes that are triggered by interactions with other molecules.
Insights into protein dynamics and interactions enable the understanding of certain pathologies,
which may be caused by the deregulation of protein ...
19. Web Accessible Image Similarity Measurements
Antoine Vandecreme, Paul Khouri Saba, Benjamin J Long, Joe Chalfoun, Peter Bajcsy, Mary C Brady
20. Evaluation of Fault Detection Effectiveness for Combinatorial and Exhaustive Selection of Discretized Test Inputs
Carmelo Montanez-Rivera, David R Kuhn, Mary C Brady, Richard M Rivello, Jenise Reyes Rodriguez, Michael K. Powers
Testing components of web browsers and other graphical interface software can be extremely expensive because of the need for human review of screen appearance and interactive behavior.
Combinatorial testing has been advocated as a method that provid ...
