    • Carcinoma cell line discrimination in microscopic images using unbalanced wavelets 

      Keskin F.; Suhre, A.; Erşahin, T.; Çetin-Atalay R.; Çetin, A. E. (2012)
      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. E. (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 O.; Çetin, A.E. (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 

      Sener, E.; Yücel, U.C.; Aksoy, S.; Büyükgebiz I.; Uzun, B.; Duygulu P. (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 F.; Cetin, A.E.; Ersahin, T.; Cetin-Atalay, R. (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 U.; Ulusoy, Ö. (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 ...
    • New face representation using compressive sensing 

      Eleyan, A.; Köse, K.; Enis Çetin, A. (2011)
      GMM supervectors are among the most popular feature sets used in SVM-based text-independent speaker verification. Most of the studies represent speaker characteristics obtained from a long recording with a single ...
    • Real-time wildfire detection using correlation descriptors 

      Habiboglu, Y.H.; Gunay O.; Cetin, A.E. (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.E. (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 ...
    • 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 

      Iscen, A.; Armagan, A.; Duygulu, P. (IEEE Computer Society, 2014)
      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 ...
    • Word retrieval in Ottoman documents 

      Arifoǧlu, D.; Duygulu, P. (2011)
      In this paper, two image matching methods are adapted to retrieve words in Ottoman documents. The first method is based on Dynamic Time Warping (DTW) method proposed in [7], while the second method is based on the Shape ...
