1. SHREC‰14 Track: Retrieval and classification on Textured 3D Models
Topic: Data Mining
Published: 6/12/2014
Author: Afzal A Godil
Abstract: This contribution reports the results of the SHREC 2014 track: Retrieval and classification on textured 3D models, whose goal is to evaluate the performance of retrieval algorithms when models vary either by geometric shape or texture, or both. The ...

2. Machine Learning Analysis for Identification of Cell Shape Metrics Associated with Stem Cell Differentiation in Nanofiber Scaffolds
Topic: Data Mining
Published: 4/19/2014
Authors: Desu Chen, Sumona Sarkar, Stephen J Florczyk, Subhadip Bodhak, Carl George Simon Jr, Joy P Dunkers, Julian Candia, Wolfgang Losert
Abstract: Cell shape has been demonstrated to be closely related to cell function and may be an important predictor of cell fate. Many metrics are available to describe cell shape, however the relationship of these metrics to cell fate are not well understood ...

3. Feature Measures for the Segmentation of Neuronal Membrane using Machine Learning Algorithm
Topic: Data Mining
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 ...

4. Multilingual Summarization: Dimensionality Reduction and a Step Towards Optimal Term Coverage
Topic: Data Mining
Published: 8/9/2013
Authors: Yi-Kai Liu, John M Conroy, Sashka T. Davis, Jeff Kubina, Dianne P. O'Leary, Judith D. Schlesinger
Abstract: In this paper we present three term weighting approaches for multi-lingual document summarization and give results on the DUC 2002 data as well as on the 2013 Multilingual Wikipedia feature articles data set. We introduce a new interval-bounded n ...

5. Hybrid shape descriptor and meta similarity generation for non-rigid and partial 3D model retrieval
Topic: Data Mining
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 ...

6. CM-BOF: Visual Similarity based 3D Shape Retrieval Using Clock Matching and Bag-of-Features
Topic: Data Mining
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 ...

7. SHREC‰13 Track: Large Scale Sketch-Based 3D Shape Retrieval
Topic: Data Mining
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 ...

8. Evaluating Real-Time Search over Tweets
Topic: Data Mining
Published: 12/10/2012
Authors: Ian M Soboroff, Dean Paul McCullough, Jimmy Lin, Craig Macdonald, Iadh Ounis, Richard McCreadie
Abstract: Twitter offers a phenomenal platform for the social sharing of information. We describe new resources that have been created in the context of the Text Retrieval Conference (TREC) to support the academic study of Twitter as a real-time information so ...

9. A comparison of methods for Non-rigid 3D shape retrieval
Topic: Data Mining
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 ...

10. An evaluation of local shape descriptors for 3D shape retrieval
Topic: Data Mining
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 ...
