1. Image Classification of Vascular Smooth Muscle Cells
Topic: Imaging
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 ...

2. 3D shape retrieval based on Multi-scale Integral Orientations
Topic: Imaging
Published: 5/2/2010
Authors: Afzal A Godil, Stephane Bres, Asim Wagan
Abstract: In this paper we describe a novel 3D shape retrieval method based on Multi-scale Integral Orientations. In our approach, a 3D model after normalization is represented by a set of depth images captured uniformly on a unit circle. Then the shape descri ...

3. A 1D Spectral Image Validation/Verification Metric for Fingerprints
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7599
Topic: Imaging
Published: 8/19/2009
Authors: John M Libert, John Donald Grantham, Shahram Orandi
Abstract: Image validation and verification are important functions in the acquisition of fingerprint images from live-scan devices and for assessing and maintaining the fidelity of fingerprint image databases. In addition to law enforcement, such databases ar ...

4. A Benchmark for Best View Selection of 3D Objects
Topic: Imaging
Published: 12/23/2010
Authors: Helin Dutagaci, Chun Pan (Benny) Cheung, Afzal A Godil
Abstract: The best view selection corresponds to the task of automatically selecting the most representative view of a 3D model. In this paper, we describe a benchmark for evaluation of best view selection algorithms. The benchmark consists of the preferred vi ...

5. A Flexible and Efficient Numerical Framework for Image Segmentation by Energy Minimization
Topic: Imaging
Published: 8/22/2010
Author: Gunay Dogan
Abstract: A widely used approach to image segmentation is to define corresponding segmentation energies and to compute shapes that are minimizers of these energies. In this work, we introduce a flexible and efficient numerical framework for minimization of suc ...

6. A Hybrid CPU-GPU Approach to Fourier-Based Image Stitching of Optical Microscopy Images
Topic: Imaging
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 ...

7. A Hybrid CPU-GPU System for Fourier-Based Stitching of Optical Microscopy Images
Topic: Imaging
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 New Convexity Measurement for 3D Meshes
Topic: Imaging
Published: 6/16/2012
Authors: Afzal A Godil, Zhouhui Lian
Abstract: This paper presents a novel convexity measurement for 3D meshes. The new convexity measure is calculated by minimizing the ratio of the summed area of valid regions in a mesh‰s six views, which are projected on faces of the bounding box whose edg ...

9. A Spectral Analytic Method for Fingerprint Image Sample Rate Estimation
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7968
Topic: Imaging
Published: 2/25/2014
Authors: John M Libert, Shahram Orandi, John Donald Grantham, Michael D Garris
Abstract: This study examines the use of the NIST Spectral Image Validation and Verification (SIVV) metric for the application of detecting the sample rate of a given fingerprint digital image. SIVV operates by reducing an input image to a 1-dimensional po ...

10. A comparison of methods for Non-rigid 3D shape retrieval
Topic: Imaging
Published: 9/26/2012
Authors: Zhouhui Lian, Afzal A Godil
Abstract: Non-rigid 3D shape retrieval has become an active and important research topic in content-based 3D object retrieval. The aim of this paper is to measure and compare the performance of state-of-the-art methods for non-rigid 3D shape retrieval. The pa ...
