11. Predicting Segmentation Accuracy for Biological Cell Images
Published: 11/29/2010
Authors: Adele P Peskin, Alden A Dima, Joe Chalfoun
Abstract: We have performed image segmentations on a very large number of images, using a wide variety of imaging conditions and cell lines, in order to study trends in the segmentation results and make predictions about segmentation accuracy. Comparing result ...

12. A Human Inspired Local Ratio-Based Algorithm for Edge Detection in Fluorescent Cell Images
Published: 11/25/2010
Authors: Adele P Peskin, Joe Chalfoun, Alden A Dima, John T Elliott, James J Filliben
Abstract: We have developed a new semi-automated method for segmenting images of biological cells seeded at low density on tissue culture substrates, which we use to improve the generation of reference data for the evaluation of automated segmentation algor ...

13. Image Classification of Vascular Smooth Muscle Cells
Published: 11/11/2010
Authors: Michael Grasso, Ronil Mokashi , Alden A Dima, Antonio Cardone, Kiran Bhadriraju, Anne L Plant, Mary C Brady, Yaacov Yesha, Yelena Yesha
Abstract: The traditional method of cell microscopy can be subjective, due to observer variability, a lack of standardization, and a limited feature set. To address this challenge, we developed an image classifier using a machine learning approach. Our system ...

14. Overlap-Based Cell Tracker
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7663
Published: 2/2/2010
Authors: Joe Chalfoun, Antonio Cardone, Alden A Dima, Michael W Halter, Daniel P Allen
Abstract: In order to facilitate the extraction of quantitative data from live cell image sets, automated image analysis methods are needed. This paper presents an introduction to the general principle of an overlap cell tracking software developed by NIST. Th ...

15. A Quality Pre-Processor for Biological Cell Images
Published: 11/30/2009
Authors: Adele P Peskin, Karen Kafadar, Alden A Dima
Abstract: We have developed a method to rapidly test the quality of a biological image, to identify appropriate segmentation methods, if any, that will render high quality segmentations for the cells within that image. The key contribution is the development o ...

16. Modeling Clinical Tumors to Create Standardized Data for Tumor Volume Measurement
Published: 11/29/2009
Authors: Adele P Peskin, Alden A Dima
Abstract: Expanding on our previously developed method for inserting synthetic objects into clinical computerized tomographic (CT) data, we model a set of eight clinical tumors that span a range of geometries and locations within the lung. The goal is to creat ...

17. Synthetic Lung Tumor Data Sets for Comparison of Volumetric Algorithms
Published: 7/13/2009
Authors: Adele P Peskin, Alden A Dima, Javier Bernal, David E. Gilsinn, Karen Kafadar
Abstract: The change in pulmonary nodules over time is an important indicator of malignant tumors. It is therefore important to be able to measure change in the size of tumors from computed tomography (CT) data taken at different times and on potentially dif ...

18. A New Protocol for Semi-Automatic Generation of Reference Data for High Resolution Biological Images
Published: 11/30/2008
Authors: Adele P Peskin, Joe Chalfoun, Alden A Dima, James J Filliben
Abstract: We compare manually segmented masks of cell images that are independently hand-selected by several different people, with a new semi-automated method for estimating reference data for images of cells with very sharp clear edges. By quantifying the la ...

19. A Win32-based Technique for Finding and Hashing NTFS Alternate Data Streams
Published: 1/24/2007
Author: Alden A Dima
Abstract: As part of an effort to create new datasets for the computer forensic community, the National Software Reference Library created a simple Windows specific tool for internal use similar to md5deep, which is able to recursively walk an NTFS file syste ...

20. Using Intelligent Agents to Assess Pervasive Computing Technologies
Published: 1/1/2001
Authors: L P Ciarletta, Alden A Dima, V P Iordanov
Abstract: Pervasive Computing (a.k.a. Ubiquitous or Ambient Computing) is a new field of computer science generally considered to lie at the intersection of desktop computing, networking, and embedded systems. Related to pervasive computing are Intelligent Env ...
