Call for Papers, Posters and System Demonstrations Authors are invited to submit original and unpublished research and practical applications in all areas of 3D Object Retrieval. Submissions are invited in form of full and short papers, as well as poster and system presentations. Suggested topics include, but are not limited to: - 3D object similarity and matching - 3D object classification, indexing, and mining - Similarity of non-rigid shapes - Feature extraction, decomposition, and segmentation - Multi-level representations for matching and retrieval - Partial, part-in-whole, and many-to-many matching - Matching under uncertainty and noise - Semantics-driven 3D object retrieval and classification - Sketch-based retrieval - Query interfaces and search modalities - Benchmarking issues - Relevance feedback methods - Active learning - Generative/discriminative approaches in 3D object categorization - Applications in multimedia, CAD, games, biometrics, e-science, e-learning, medicine, biology, and cultural heritage. This year\'s workshop will also feature the 6th Shape Retrieval Evaluation Contest (SHREC\'2011). A separate call for participation will be issued later on. Extended versions of selected papers from the Workshop will appear, after a further review, in a special issue of The Visual Computer Journal published by Springer. # Important dates December 1, 2010: Submissions due January 20, 2011: Notification of acceptance February 1, 2011: Camera-ready papers April 10, 2011: Workshop takes place # Organization Chairs Hamid Laga (Tokyo Institute of Technology, Japan) Tobias Schreck (Technische Universitaet Darmstadt, Germany) Programme Chairs Alfredo Ferreira (IST/Technical University of Lisbon, Portugal) Afzal Godil (National Institute of the Standards and Technology, USA) Ioannis Pratikakis (Democritus University of Thrace, Greece) Program Committee Ceyhun Burak Akgul (Vistek-ISRA Vision, Turkey) Filipos Azariadis (University of the Aegean, Greece) Benjamin Bustos (University of Chile, Chile) Mohamed Daoudi (TELECOM Lille1/LIFL, France) Dieter W.
