    • 3D human pose search using oriented cylinders 

      Pehlivan, Selen; Duygulu, Pınar (IEEE, 2009-09-10)
      In this study, we present a representation based on a new 3D search technique for volumetric human poses which is then used to recognize actions in three dimensional video sequences. We generate a set of cylinder like 3D ...
    • Compressive sensing based flame detection in infrared videos 

      Günay, Osman; Çetin, A. Enis (IEEE, 2013)
      In this paper, a Compressive Sensing based feature extraction algorithm is proposed for flame detection using infrared cameras. First, bright and moving regions in videos are detected. Then the videos are divided into ...
    • Contour based smoke detection in video using wavelets 

      Toreyin, B. U.; Dedeoglu, Y.; Cetin, A. E. (2006)
      This paper proposes a novel method to detect smoke in video. It is assumed the camera monitoring the scene is stationary. The smoke is semi-transparent at the early stages of a fire. Therefore edges present in image frames ...
    • Flame detection in video using hidden Markov models 

      Töreyin, B. U.; Dedeoğlu, Y.; Çetin, A. E. (Institute of Electrical and Electronics Engineers, 2005)
      This paper proposes a novel method to detect flames in video by processing the data generated by an ordinary camera monitoring a scene. In addition to ordinary motion and color clues, flame flicker process is also detected ...
    • Flame detection system based on wavelet analysis of PIR sensor signals with an HMM decision mechanism 

      Ug̃ur Töreyin, B.; Birey Soyer, E.; Urfaliog̃lu O.; Enis Çetin, A. (2008)
      In this paper, a flame detection system based on a pyroelectric (or passive) infrared (PIR) sensor is described. The flame detection system can be used for fire detection in large rooms. The flame flicker process of an ...
    • Flame detection using PIR sensors 

      Uǧur Töreyin, B.; Birey Soyer, E.; Urfalioǧlu O.; Enis Çetin, A. (2008)
      In this paper, a flame detection system based on a pyroelectric (or passive) infrared (PIR) sensor is described. The flame detection system can be used for fire detection in large rooms. The flame flicker process of an ...
    • HMM based falling person detection using both audio and video 

      Töreyin, B. Uğur; Dedeoğlu, Yiğithan; Çetin, A. Enis (IEEE, 2006)
      Automatic detection of a falling person in video is an important problem with applications in security and safety areas including supportive home environments and CCTV surveillance systems. Human motion in video is modeled ...
    • HMM based method for dynamic texture detection 

      Töreyin, Behçet Uğur; Çetin, Ahmet 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 ...
    • A hybrid SVM/HMM based system for the state detection of individual finger movements from multichannel ECoG signals 

      Onaran, İbrahim; Ince, N.F.; Çetin, A. Enis; Abosch, A. (IEEE, 2011)
      A hybrid state detection algorithm is presented for the estimation of baseline and movement states which can be used to trigger a free paced neuroprostethic. The hybrid model was constructed by fusing a multiclass Support ...
    • A novel model-based method for feature extraction from protein sequences for classification 

      Saraç Ö.S.; Atalay V.; Atalay, R.Ç. (2006)
      Representation of amino-acid sequences constitutes the key point in classification of proteins into functional or structural classes. The representation should contain the biologically meaningful information hidden in the ...
    • Wavelet based detection of moving tree branches and leaves in video 

      Toreyin, B.U.; Cetin, A.E. (2006)
      A method for detection of tree branches and leaves in video is proposed. It is observed that the motion vectors of tree branches and leaves exhibit random motion. On the other hand regular motion of green colored objects ...
