Report Number: 7939
Topic: Imaging
Published: 8/27/2013
Authors: John M Libert, Shahram Orandi, Michael D Garris, John D. Grantham
Abstract: As part of NIST‰s investigative efforts to support development of the FBI Next Generation Identification (NGI) systems, this investigation evaluates effects on image fidelity of wavelet transform decomposition and quality layer options for JPEG 2 ...

33. Efficient Motion Vector Interpolation for Error Concealment of H.264/AVC
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7733
Topic: Imaging
Published: 3/1/2011
Author: Hamid Gharavi
Abstract: In video communications the compressed video stream is very likely to be corrupted by channel errors. In order to combat these channel errors, many methods have been proposed. In this paper, a new method for motion vectors (MVs) interpolation with th ...

34. Evaluating Form Designs for Optical Character Recognition
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 5364
Topic: Imaging
Published: 2/1/1994
Author: Michael D Garris

35. Evaluation of 3D Interest Point Detection Techniques
Topic: Imaging
Published: 4/7/2011
Authors: Helin Dutagaci, Chun Pan (Benny) Cheung, Afzal A Godil
Abstract: In this paper, we compare the results of five 3D interest point detection techniques to the interest points marked by human subjects. This comparison is used to quantitatively evaluate the interest point detection algorithms. We asked human subjects ...

36. Evaluation of 3D Interest Point Detection Techniques via Human-generated Ground Truth
Topic: Imaging
Published: 6/29/2012
Authors: Afzal A Godil, Helin Dutagaci
Abstract: In this paper, we present an evaluation strategy based on human-generated ground truth to measure the performance of 3D interest point detection techniques. We provide quantitative evaluation measures that relate automatically detected interest point ...

37. Exploring Local Features and the Bag-of-Visual-Words Approach for BioImage Classification
Topic: Imaging
Published: 11/5/2013
Authors: Afzal A Godil, Asim Wagan
Abstract: With recent advances in imaging technologies large numbers of bioimages are currently being acquired. Automated classification of these bio-images is a very important and challenging problem. Here we investigate the capabilities of local features a ...

38. Facial Shape Analysis and Sizing System
Topic: Imaging
Published: 7/24/2009
Author: Afzal A Godil
Abstract: The understanding of shape and size of the human head and faces is vital for design of facial wear products, such as respirators, helmets, eyeglasses and for ergonomic studies. 3D scanning is used to create 3D databases of thousands of humans from ...

39. Feature Measures for the Segmentation of Neuronal Membrane using Machine Learning Algorithm
Topic: Imaging
Published: 1/6/2014
Authors: Afzal A Godil, Saadia S. Iftikhar
Abstract: In this paper, we present a Support Vector Machine (SVM) based pixel classifier for a semi-automated segmentation algorithm to detect neuronal membrane structures in stacks of electron microscopy images of brain tissue samples. This algorithm uses ...

40. Feature-preserved 3D Canonical Form
Topic: Imaging
Published: 7/28/2012
Authors: Afzal A Godil, Zhouhui Lian
Abstract: Abstract Measuring the dissimilarity between non-rigid objects is a challenging problem in 3D shape retrieval. One potential solution is to construct the models‰ 3D canonical forms (i.e., isometry-invariant representations in 3D Euclidean domain) on ...
