    • Finding faces in news photos using both face and name information 

      Ozkan, D.; Duygulu P. (2006)
      We propose a method to associate names and faces for querying people in large news photo collections. On the assumption that a person's face is likely to appear when his/her name is mentioned in the caption, first all the ...
    • Finding people frequently appearing in news 

      Ozkan, D.; Duygulu, P. (Springer, 2006)
      We propose a graph based method to improve the performance of person queries in large news video collections. The method benefits from the multi-modal structure of videos and integrates text and face information. Using the ...

    • Human eye localization using edge projections 

      Türkan, M.; Pardàs, M.M.; Çetin, A. E. (2007)
      in this paper, a human eye localization algorithm in images and video is presented for faces with frontal pose and upright orientation. A given face region is filtered by a high-pass filter of a wavelet transform. In this ...
    • Human face detection in video using edge projections 

      Türkan, M.; Dülek, B.; Onaran I.; Çetin, A.E. (2006)
      In this paper, a human face detection method in images and video is presented. After determining possible face candidate regions using color information, each region is filtered by a high-pass filter of a wavelet transform. ...
    • Image feature extraction using 2D mel-cepstrum 

      Çakir, S.; Çetin, A.E. (2010)
      In this paper, a feature extraction method based on two-dimensional (2D) mel-cepstrum is introduced. Feature matrices resulting from the 2D mel-cepstrum, Fourier LDA approach and original image matrices are individually ...
    • Image feature extraction using compressive sensing 

      Eleyan, A.; Kose, K.; Cetin, A.E. (Springer Verlag, 2014)
      In this paper a new approach for image feature extraction is presented. We used the Compressive Sensing (CS) concept to generate the measurement matrix. The new measurement matrix is different from the measurement matrices ...
    • Improvement of face detection algorithms for news videos 

      Ikizler, N.; Duygulu P. (2005)
