21. Understanding impact of image quality on segmentation accuracy
Topic: Imaging
Published: 8/6/2013
Authors: YaShian Li-Baboud, Antonio Cardone, Joe Chalfoun, Peter Bajcsy, John T Elliott
Abstract: We introduce a methodology for microscopy settings assessment and segmentation accuracy prediction based on image quality descriptors.

22. Hybrid shape descriptor and meta similarity generation for non-rigid and partial 3D model retrieval
Topic: Imaging
Published: 7/26/2013
Author: Afzal A Godil
Abstract: Non-rigid and partial 3D model retrieval are two significant and challenging research directions in the field of 3D model retrieval. Little work has been done in proposing a hybrid shape descriptor that works for both retrieval scenarios, let alone ...

23. Non-Rigid and Partial 3D Model Retrieval Using Hybrid Shape Descriptor and Meta Similarity
Topic: Imaging
Published: 7/26/2013
Authors: Bo Li, Afzal A Godil, Henry Johan
Abstract: Non-rigid and partial 3D model retrieval are two significant and challenging research directions in the field of 3D model retrieval. Little work has been done in proposing a hybrid shape descriptor that works for both retrieval scenarios, let alo ...

24. Shape Calculus for Shape Energies in Image Processing
Topic: Imaging
Published: 7/22/2013
Authors: Gunay Dogan, Ricardo H. Nochetto
Abstract: Many image processing problems are naturally expressed as energy minimization or shape optimization problems, in which the free variable is a shape, such as a curve in 2d or a surface in 3d. Examples are image segmentation, multiview stereo reconstru ...

25. CM-BOF: Visual Similarity based 3D Shape Retrieval Using Clock Matching and Bag-of-Features
Topic: Imaging
Published: 6/6/2013
Authors: Afzal A Godil, Zhouhui Lian
Abstract: Content-based 3D object retrieval has be- come an active topic in many research communities. In this paper, we propose a novel visual similarity based 3Dshaperetrievalmethod(CM-BOF)usingClockMatch- ing and Bag-of-Features. Specifically, pose normal ...

26. SHREC‰13 Track: Large Scale Sketch-Based 3D Shape Retrieval
Topic: Imaging
Published: 6/6/2013
Authors: Afzal A Godil, Bo Li , Yijuan Lu, Tobias Schreck
Abstract: Sketch-based 3D shape retrieval has become an important research topic in content-based 3D object retrieval. The aim of this track is to measure and compare the performance of sketch-based 3D shape retrieval methods based on a large scale hand-draw ...

27. In-plane Rotation and Scale Invariant Clustering and Dictionary Learning
Topic: Imaging
Published: 6/3/2013
Authors: P Jonathon Phillips, Challa Sastry, Yi-Chen Chen, Vishal M Patel, Rama Chellappa
Abstract: n this paper, we present an approach that simulta- neously clusters images and learns dictionaries from the clusters. The method learns dictionaries in the Radon transform domain, while clustering in the image domain. The main feature of the proposed ...

28. 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 ...

29. 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 R. Goasmat, Hui Zhou, Martin Y 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 ...

30. 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 ...
