    • BilVideo: Design and implementation of a video database management system 

      Dönderler, M. E.; Şaykol, E.; Arslan, U.; Ulusoy, Özgür; Güdükbay, Uğur (Springer, 2005)
      With the advances in information technology, the amount of multimedia data captured, produced, and stored is increasing rapidly. As a consequence, multimedia content is widely used for many applications in today's world, ...

    • HMM based method for dynamic texture detection 

      Töreyin, Behçet Uğur; Çetin, A. Enis (IEEE, 2007)
      A method for detection of dynamic textures in video is proposed. It is observed that the motion vectors of most of the dynamic textures (e.g. sea waves, swaying tree leaves and branches in the wind, etc.) exhibit random ...

    • MPEG-7 uyumlu video veri tabanlari için önemli nesnelerin otomatik olarak bulunmasi 

      Baştan, Muhammed; Güdükbay, Uğur; Ulusoy, Özgür (IEEE, 2008-04)
      Bu çalışma, genel olarak nesneye dayalı endekslemeyi destekleyen, özel olarak MPEG-7 uyumlu veritabanları için, videolardan önemli nesnelerin otomatik olarak çıkarılmasını saglayabilecek bir yöntem sunmaktadır. Şimdiye ...

    • Object-oriented texture analysis for the unsupervised segmentation of biopsy images for cancer detection 

      Tosun, A. B.; Kandemir, M.; Sokmensuer, C.; Gunduz Demir, C. (Elsevier BV, 2009-06)
      Staining methods routinely used in pathology lead to similar color distributions in the biologically different regions of histopathological images. This causes problems in image segmentation for the quantitative analysis ...

    • Segmentation-based extraction of important objects from video for object-based indexing 

      Baştan, Muhammet; Güdükbay, Uğur; Ulusoy, Özgür (IEEE, 2008-06)
      We describe a method to automatically extract important video objects for object-based indexing. Most of the existing salient object detection approaches detect visually conspicuous structures in images, while our method ...

    • Texture mapping on geometrical models 

      Açıkgöz, Oktay Aydın (Bilkent University, 1989)
      The contribution of the visual effects of textures is an important aspect in generating images of real objects. Texture mapping is a very successful technique in this respect. Texture mapping can be subdivided into ...

    • Texturing of titanium (Ti6Al4V) medical implant surfaces with MHz-repetition-rate femtosecond and picosecond Yb-doped fiber lasers 

      Erdoǧan, M.; Öktem, B.; Kalaycioǧlu H.; Yavaş, S.; Mukhopadhyay P.K.; Eken, K.; Özgören, K.; Aykaç, Y.; Tazebay, U.H.; Ilday F.O. (Optical Society of American (OSA), 2011)
      We propose and demonstrate the use of short pulsed fiber lasers in surface texturing using MHz-repetition-rate, microjoule- and sub-microjoule-energy pulses. Texturing of titanium-based (Ti6Al4V) dental implant surfaces ...

    • Tissue object patterns for segmentation in histopathological images 

      Gündüz-Demir, Çiğdem (ACM, 2011)
      In the current practice of medicine, histopathological examination is the gold standard for routine clinical diagnosis and grading of cancer. However, as this examination involves the visual analysis of biopsies, it is ...

    • Unsupervised tissue image segmentation through object-oriented texture 

      Tosun, Akif Burak; Sokmensuer, C.; Gündüz-Demir, Çiğdem (IEEE, 2010)
      This paper presents a new algorithm for the unsupervised segmentation of tissue images. It relies on using the spatial information of cytological tissue components. As opposed to the previous study, it does not only use ...

    • Wavelet domain textual coding of Ottoman script images 

      Gerek, Ömer. N.; Çetin, A. Enis; Tewfik, A. H. (SPIE, 1996-03)
      Image coding using wavelet transform, DCT, and similar transform techniques is well established. On the other hand, these coding methods neither take into account the special characteristics of the images in a database nor ...
