    • Carcinoma cell line discrimination in microscopic images using unbalanced wavelets 

      Keskin, Furkan; Suhre, Alexander; Erşahin, Tüli,; Çetin Atalay, Rengül; Çetin, A. Enis (IEEE, 2012-03)
      Cancer cell lines are widely used for research purposes in laboratories all over the world. In this paper, we present a novel method for cancer cell line image classification, which is very costly by conventional methods. ...
    • Covariance matrix-based fire and flame detection method in video 

      Habiboğlu, Y. H.; Günay, O.; Çetin, A. Enis (Springer, 2011-09-17)
      This paper proposes a video-based fire detection system which uses color, spatial and temporal information. The system divides the video into spatio-temporal blocks and uses covariance-based features extracted from these ...
    • Flame detection method in video using covariance descriptors 

      Habiboǧlu, Y.H.; Günay, Osman; Çetin, A. Enis (IEEE, 2011)
      Video fire detection system which uses a spatio-temporal covariance matrix of video data is proposed. This system divides the video into spatio-temporal blocks and computes covariance features extracted from these blocks ...
    • Labeling of faces in personal photo albums 

      Şener, Emre; Yücel, Utku Can; Aksoy, Sercan; Büyükgebiz, ibrahim; Uzun, Burak; Duygulu, Pınar (IEEE, 2013)
      In this study, we propose a system for organizing personal photo collections. Motivated with the fact that people related queries are the most desired ones, we propose a method for labeling faces in photographs. After ...
    • Microscopic image classification via WT-based covariance descriptors using Kullback-Leibler distance 

      Keskin, Furkan; Çetin, A. Enis; Erşahin, Tülin; Çetin-Atalay, Rengül (IEEE, 2012)
      In this paper, we present a novel method for classification of cancer cell line images using complex wavelet-based region covariance matrix descriptors. Microscopic images containing irregular carcinoma cell patterns are ...
    • Nearest-neighbor based metric functions for indoor scene recognition 

      Cakir, F.; Güdükbay, Uğur; Ulusoy, Özgür (Academic Press, 2011)
      Indoor scene recognition is a challenging problem in the classical scene recognition domain due to the severe intra-class variations and inter-class similarities of man-made indoor structures. State-of-the-art scene ...
    • Osmanlica belgelerde kelime erişimi 

      Arifoǧlu, Damla; Duygulu, Pınar (IEEE, 2011-04)
      Bu çalışmada, Osmanlıca arşivlerinin analizi amacıyla, kelime erişimi problemi iki farklı resim eşleme yöntemi ile çözülmeye çalışılmaktadır. Bu amaçla (1) Dinamik Zaman Bükmesi (DZB) tabanlı kelime eşleme yöntemi [7] ve ...
    • Real-time wildfire detection using correlation descriptors 

      Habiboğlu, Y. Hakan; Günay, Osman; Çetin, A. Enis (IEEE, 2011)
      A video based wildfire detection system that based on spatio-temporal correlation descriptors is developed. During the initial stages of wildfires smoke plume becomes visible before the flames. The proposed method uses ...
    • Region covariance descriptors calculated over the salient points for target tracking 

      Çakir, S.; Aytaç, T.; Yildirim, A.; Beheshti, S.; Gerek Ö.N.; Çetin, A. Enis (IEEE, 2012)
      Features extracted at salient points in the image are used to construct region covariance descriptor (RCD) for target tracking purposes. In the classical approach, the RCD is computed by using the features at each pixel ...
    • Sıkıştırılmış algılama kullanarak yeni bir yüz gösterimi 

      Eleyan, A.; Köse, Kıvanç; Çetin, A. Enis (IEEE, 2011-04)
      Bu bildiride yüz resimleri için yeni bir tanımlayıcı sunulmaktadır. Sıkıştırılmış Algılama (Compressive Sensing) fikri kullanılarak, yüz imgelerinden öznitelikler çıkarılmıştır. Öznitelik çıkarımı sırasında Rastgele Gauss ...
    • Understanding responses to materials and colors in interiors 

      Ulusoy, B.; Olguntürk, N. (Wiley, 2017)
      This article investigates the free associations of materials and colors in the context of interior architecture. Materials and colors rarely appear alone in interiors; therefore, in the scope of this study, the researchers ...
    • What is usual in unusual videos? trajectory snippet histograms for discovering unusualness 

      İşcen, Ahmet; Armağan, Anıl; Duygulu, Pınar (IEEE, 2014-06)
      Unusual events are important as being possible indicators of undesired consequences. Moreover, unusualness in everyday life activities may also be amusing to watch as proven by the popularity of such videos shared in social ...
