    • Automatic multimedia cross-modal correlation discovery 

      Pan, J.-Y.; Yang, H.-J.; Faloutsos, C.; Duygulu, Pınar (ACM, 2004-08)
      Given an image (or video clip, or audio song), how do we automatically assign keywords to it? The general problem is to find correlations across the media in a collection of multimedia objects like video clips, with colors, ...
    • COST292 experimental framework for TRECVID 2006 

      Ćalić J.; Krämer P.; Naci, U.; Vrochidis, S.; Aksoy, S.; Zhangk Q.; Benois-Pineau J.; Saracoglu, A.; Doulaverakis, C.; Jarina, R.; Campbell, N.; Mezaris V.; Kompatsiaris I.; Spyrou, E.; Koumoulos G.; Avrithis, Y.; Dalkilic, A.; Alatan, A.; Hanjalic, A.; Izquierdo, E. (National Institute of Standards and Technology, 2006)
      In this paper we give an overview of the four TRECVID tasks submitted by COST292, European network of institutions in the area of semantic multimodal analysis and retrieval of digital video media. Initially, we present ...
    • Database research at Bilkent University 

      Ulusoy, Özgür (ACM, 2005)
      The research activities of the Database Research Group of Bilkent University are discussed. The research is mainly focused on the topics of multimedia databases, Web databases, and mobile computing. The Ottoman Archive ...
    • Finding people frequently appearing in news 

      Özkan, Derya; Duygulu, Pınar (Springer, 2006-07)
      We propose a graph based method to improve the performance of person queries in large news video collections. The method benefits from the multi-modal structure of videos and integrates text and face information. Using the ...
    • Image sequence analysis for emerging interactive multimedia services-the European COST 211 framework 

      Alatan, A. A.; Onural, L.; Wollborn, M.; Mech, R.; Tuncel, E.; Sikora, T. (Institute of Electrical and Electronics Engineers, 1998-11)
      Flexibility and efficiency of coding, content extraction, and content-based search are key research topics in the field of interactive multimedia. Ongoing ISO MPEG-4 and MPEG-7 activities are targeting standardization to ...
    • Intracavity optical trapping with ytterbium doped fiber 

      Laser, R.; Sayed, R.; Kalantarifard, Fatemeh; Elahi P.; İlday, F. Ömer; Volpe, Giovanni; Marago O.M. (SPIE, 2013)
      We propose a novel approach for trapping micron-sized particles and living cells based on optical feedback. This approach can be implemented at low numerical aperture (NA=0.5, 20X) and long working distance. In this ...
    • Making peace with your multimedia 

      Adali, S. (1998)
      [No abstract available]
    • A performance evaluation framework of a rate-controlled MPEG video transmission over UMTS networks 

      Akar, Nail; Barbera, M.; Budzisz, L.; Ferrùs, R.; Kankaya, Emre; Schembra, G. (IEEE, 2007-07)
      UMTS is designed to offer high bandwidth radio access with QoS assurances for multimedia communications. In particular, real-time video communications services are expected to become a successful experience under UMTS ...
    • Recognizing objects and scenes in news videos 

      Baştan, Muhammet; Duygulu, Pınar (Springer, 2006-07)
      We propose a new approach to recognize objects and scenes in news videos motivated by the availability of large video collections. This approach considers the recognition problem as the translation of visual elements to ...
    • A simple and effective mechanism for stored video streaming with TCP transport and server-side adaptive frame discard 

      Gürses, E.; Akar, G. B.; Akar, N. (Elsevier, 2005)
      Transmission control protocol (TCP) with its well-established congestion control mechanism is the prevailing transport layer protocol for non-real time data in current Internet Protocol (IP) networks. It would be desirable ...
    • Towards auto-documentary: Tracking the evolution of news stories 

      Duygulu, Pınar; Pan J.-Y.; Forsyth, D.A. (ACM, 2004)
      News videos constitute an important source of information for tracking and documenting important events. In these videos, news stories are often accompanied by short video shots that tend to be repeated during the course ...
    • Utilization of the recursive shortest spanning tree algorithm for video-object segmentation by 2-D affine motion modeling 

      Tuncel, E.; Onural, L. (IEEE, 2000)
      A novel video-object segmentation algorithm is proposed, which takes the previously estimated 2-D dense motion vector field as input and uses the generalized recursive shortest spanning tree method to approximate each ...
