1. Dictionary Learning from Ambiguously Labeled Data
Topic: Imaging
Published: 4/9/2013
Authors: P Jonathon Phillips, Yi-Chen Chen, Vishal M Patel, Jaishanker K Pillai, Rama Chellappa
Abstract: We propose a novel dictionary-based learning method for ambiguously labeled multiclass classification, where each training sample has multiple labels and only one of them is the correct label. The dictionary learning problem is solved using an iterat ...

2. SCATTERFIELD MICROSCOPY, REVIEW OF TECHNIQUES THAT PUSH THE FUNDAMENTAL LIMITS OF OPTICAL DEFECT METROLOGY
Topic: Imaging
Published: 3/25/2013
Authors: Richard M Silver, Bryan M Barnes, Francois Romain Francis Goasmat, Hui Zhou, Martin Yeungjoon Sohn
Abstract: The semiconductor manufacturing industry is now facing serious challenges in achieving defect detection rates with acceptable throughput and accuracy. With conventional bright-field and dark- field inspection methods now at their limits, it has b ...

3. 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 ...

4. An evaluation of local shape descriptors for 3D shape retrieval
Topic: Imaging
Published: 9/26/2012
Authors: Afzal A Godil, Sarah Y. Tang
Abstract: As the usage of 3D models increases, so does the importance of developing accurate 3D shape retrieval algorithms. A common approach is to calculate a shape descriptor for each object, which can then be compared to determine two objects’ similarity. H ...

6. An Exploration of the Operational Ramifications of Lossless Compression of 1000 ppi Fingerprint Imagery
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7779
Topic: Imaging
Published: 8/6/2012
Authors: Shahram Orandi, John M Libert, John Donald Grantham, Kenneth Ko, Stephen S Wood, Jin Chu Wu, Lindsay Meredith Petersen, Bruce Bandini
Abstract: This paper presents the findings of a study initially conducted to measure the operational impact of JPEG 2000 lossy compression on 1000 ppi fingerprint imagery at various levels of compression, but later expanded to include lossless compression. Los ...

7. 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 ...

9. 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 ...

10. 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 ...
