    • 3D model compression using connectivity-guided adaptive wavelet transform built into 2D SPIHT 

      Köse K.; Çetin, A. Enis; Güdükbay, Uğur; Onural, L. (Academic Press, 2010-01)
      Connectivity-Guided Adaptive Wavelet Transform based mesh compression framework is proposed. The transformation uses the connectivity information of the 3D model to exploit the inter-pixel correlations. Orthographic ...

    • Change detection in digital video signals 

      Zaibi, Rabi (Bilkent University, 1999)
      We present a method for scene change detection based on projections onto the vertical, horizontal and diagonal axes. At first, vertical projection of each two consecutive interframe differences are calculated. Then based ...

    • Formulations and valid inequalities for the heterogeneous vehicle routing problem 

      Yaman, H. (Springer, 2006)
      We consider the vehicle routing problem where one can choose among vehicles with different costs and capacities to serve the trips. We develop six different formulations: the first four based on Miller-Tucker-Zemlin ...

    • Projecting the flow variables for hub location problems 

      Labbé, M.; Yaman, H. (John Wiley & Sons, 2004)
      We consider two formulations for the uncapacitated hub location problem with single assignment (UHL), which use multicommodity flow variables. We project out the flow variables and determine some extreme rays of the ...

    • Zaman-frekans dağılımı için çekirdek kestirimi 

      Deprem, Zeynel; Çetin, A. Enis (IEEE, 2015-05)
      Bu dokümanda çözünürlüğü yüksek ve çapraz terim içermeyen Cohen sınıfı bir Zaman-frekans (ZF) dağılımının, çekirdek kestirim yöntemi ile elde edilmesi tanıtılmaktadır. Çekirdek kestirimi, başlangıç taslak bir zaman-frekans ...
