    • Connectivity-guided adaptive lifting transform for image like compression of meshes 

      Köse, Kıvanç; Çetin, A. Enis; Güdükbay, Uğur; Onural, Levent (IEEE, 2007-05)
      We propose a new connectivity-guided adaptive wavelet transform based mesh compression framework. The 3D mesh is first transformed to 2D images on a regular grid structure by performing orthogonal projections onto the image ...
    • İnsan hareketlerinin PIR-sensör tabanlı bir sistemle sınıflandırılması 

      Urfalıoğlu, Onay; Soyer, Emin B.; Töreyin, B. Uğur; Çetin, A. Enis (IEEE, 2008-04)
      Bu bildiride, tek bir pasif kızılberisi sensörü (PIR) kullanarak beş farklı insan hareketi ve bir hareketsiz arkaplan gürültüsünden oluşan toplam 6 çeşit olay için bir sınıflandırma yöntemi önerilmiştir. Otomatik olay ...
    • Nonrectangular wavelets for multiresolution mesh analysis and compression 

      Köse, Kıvanç; Çetin, A. Enis; Güdükbay, Uğur; Onural, Levent (IEEE, 2006)
      We propose a new Set Partitioning In Hierarchical Trees (SPIHT) based mesh compression framework. The 3D mesh is first transformed to 2D images on a regular grid structure. Then, this image-like representation is wavelet ...
    • Processing count queries over event streams at multiple time granularities 

      Ünal, A.; Saygın, Y.; Ulusoy, Özgür (Elsevier Inc., 2006-07-22)
      Management and analysis of streaming data has become crucial with its applications to web, sensor data, network traffic data, and stock market. Data streams consist of mostly numeric data but what is more interesting are ...
