    • Classification of closed-and open-shell pistachio nuts using voice-recognition technology 

      Çetin, A. Enis; Pearson, T. C.; Tewfik, A. H. (American Society of Agricultural and Biological Engineers, 2004)
      An algorithm using speech recognition technology was developed to distinguish pistachio nuts with closed shells from those with open shells. It was observed that upon impact with a steel plate, nuts with closed shells emit ...

    • Coding of fingerprint images using binary subband decomposition and vector quantization 

      Gerek, Ömer N.; Çetin, A. Enis (SPIE, 1998-01)
      In this paper, compression of binary digital fingerprint images is considered. High compression ratios for fingerprint images is essential for handling huge amount of images in databases. In our method, the fingerprint ...

    • Matching ottoman words: an image retrieval approach to historical document indexing 

      Ataer, Esra; Duygulu, Pınar (ACM, 2007-07)
      Large archives of Ottoman documents are challenging to many historians all over the world. However, these archives remain inaccessible since manual transcription of such a huge volume is difficult. Automatic transcription ...

    • Osmanlıca kelimeleri eşleme 

      Ataer, Esra; Duygulu, Pınar (IEEE, 2007-06)
      Osmanlı arşivleri dünyanın pek çok yerinden araştırmacının ilgi alanına girmektedir. Fakat bu belgelerin elle çevirisi zor bir iş olduğu için, bu arşivler kullanılamaz durumdadır. Otomatik çeviri gerekmektedir, fakat ...

    • QR-RLS algorithm for error diffusion of color images 

      Unal, G. B.; Yardimci, Y.; Arıkan, Orhan; Çetin, A. Enis (SPIE, 2000)
      Printing color images on color printers and displaying them on computer monitors requires a significant reduction of physically distinct colors, which causes degradation in image quality. An efficient method to improve the ...

    • Subband analysis for robust speech recognition in the presence of car noise 

      Çetin, A. Enis; Yardımcı, Y.; Erzin, Engin (IEEE, 1995-05)
      In this paper, a new set of speech feature representations for robust speech recognition in the presence of car noise are proposed. These parameters are based on subband analysis of the speech signal. Line Spectral Frequency ...

    • Wavelet based detection of moving tree branches and leaves in video 

      Töreyin, B. Uğur; Çetin, A. Enis (IEEE, 2006-05)
      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 ...
