Three-Dimensional Shape-Structure Comparison Method for Protein Classification
Found in: IEEE/ACM Transactions on Computational Biology and Bioinformatics
By Petros Daras, Dimitrios Zarpalas, Apostolos Axenopoulos, Dimitrios Tzovaras, Michael Gerassimos Strintzis
Issue Date:July 2006
pp. 193-207
In this paper, a 3D shape-based approach is presented for the efficient search, retrieval, and classification of protein molecules. The method relies primarily on the geometric 3D structure of the proteins, which is produced from the corresponding PDB file...
 
3D Model Watermarking for Indexing using the Generalized Radon Transform
Found in: 3D Data Processing Visualization and Transmission, International Symposium on
By Petros Daras, Dimitrios Zarpalas, Dimitrios Tzovaras, Michael G. Strintzis
Issue Date:September 2004
pp. 102-109
The present paper proposes a novel method for 3D-model watermarking for indexing. The proposed approach is based on the use of a Generalized Radon Transformation. More specifically, the Cylindrical Integration Transform (CIT) is initially applied to the 3D...
 
Shape Matching using the 3D Radon Transform
Found in: 3D Data Processing Visualization and Transmission, International Symposium on
By Petros Daras, Dimitrios Zarpalas, Dimitrios Tzovaras, Michael G. Strintzis
Issue Date:September 2004
pp. 953-960
In this paper a novel method for 3D model content-based search and retrieval based on the 3D Radon Transform and a querying-by-3D-model approach, is presented. Descriptors are extracted using the 3D Radon Transform and applying a set of functionals on the ...
 
A collaborative Wiki-based tool for semantic management of medical interventions
Found in: 2012 IEEE 12th International Conference on Bioinformatics & Bioengineering (BIBE)
By Dionysia Kontotasiou,Dimitrios Zarpalas,Charalabos Bratsas,Panagiotis D. Bamidis
Issue Date:November 2012
pp. 7-12
Semantic wikis have been widely adopted to support a variety of collaborative activities within the health domain [6], [7], [9]. In this paper, relevant existing tools that may be taken into account for the development of a Wiki-based tool are revisited. T...
 
Estimating human motion from multiple Kinect sensors
Found in: Proceedings of the 6th International Conference on Computer Vision / Computer Graphics Collaboration Techniques and Applications (MIRAGE '13)
By Anargyros Chatzitofis, Dimitrios S. Alexiadis, Dimitrios Zarpalas, Petros Daras, Stylianos Asteriadis
Issue Date:June 2013
pp. 1-6
Human motion estimation is a topic receiving high attention during the last decades. There is a vast range of applications that employ human motion tracking, while the industry is continuously offering novel motion tracking systems, which are opening new p...
     
Activity Recognition from Silhouettes using Linear Systems and Model (In)validation Techniques
Found in: Pattern Recognition, International Conference on
By Roberto Lublinerman, Necmiye Ozay, Dimitrios Zarpalas, Octavia Camps
Issue Date:August 2006
pp. 347-350
In this work we propose a model (in)validation approach to gait recognition, using a system that tries to discriminate specific activities of people. The recognition process departs from an abstraction obtained from video image sequences for different acti...

Three-dimensional monitoring of weightlifting for computer assisted training
Found in: Proceedings of the Virtual Reality International Conference: Laval Virtual (VRIC '13)
By Anargyros Chatzitofis, Dimitrios Zarpalas, Nicholas Vretos, Petros Daras
Issue Date:March 2013
pp. 1-7
This paper investigates the use of 3D information in the context of sports training. More specifically, a weightlifting athlete attempt is monitored, helping any coach to train athletes as she/he prefers. Our aim is to detect, collect and extract every use...
     
Brain structures segmentation using optimum global and local weights on mixing active contours and neighboring constraints
Found in: Proceedings of the 4th International Symposium on Applied Sciences in Biomedical and Communication Technologies (ISABEL '11)
By Anastasios Zafeiropoulos, Dimitrios Zarpalas, Michael G. Strintzis, Nicos Maglaveras, Petros Daras
Issue Date:October 2011
pp. 1-5
This paper presents a new method for segmenting multiple brain structures by using an optimized mixture of different Active Contour Models (ACMs). Prior constraints and structures' neighboring interaction are modelled for each structure. Prior information ...
