      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.; Köse, Kıvanç; Çetin, A. Enis (Springer, 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, Nazlı; Duygulu, Pınar (IEEE, 2005)
