    • Compression of images in CFA format 

      Cüce, Halil İbrahim; Çetin, Ahmet Enis; Davey, M. K. (IEEE, 2006)
      In this paper, images in Color Filter Array (CFA) format are compressed without converting them to full-RGB color images. Green pixels are extracted from the CFA image data and placed in a rectangular array, and compressed ...
    • Empirical mode decomposition aided by adaptive low pass filtering 

      Öztürk, Onur; Arıkan, Orhan; Çetin, A. Enis (IEEE, 2012)
      Empirical Mode Decomposition (EMD) is an adaptive signal analysis technique which derives its basis functions from the signal itself. EMD is realized through successive iterations of a sifting process requiring local mean ...
    • JPEG hardware accelerator design for FPGA 

      Duman, Kaan; Çoǧun, Fuat; Öktem, L. (IEEE, 2007)
      A fully pipelined JPEG hardware accelerator that runs on FPGA is presented. The accelerator is designed interactively in a simulation environment, using a DSP hardware design automation tool chain. The encoder part of the ...
    • Moving region detection in compressed video 

      Töreyin, B. U.; Cetin, A. E.; Aksay, A.; Akhan, M. B. (Springer, 2004)
      In this paper, an algorithm for moving region detection in compressed video is developed. It is assumed that the video can be compressed either using the Discrete Cosine Transform (DOT) or the Wavelet Transform (WT). The ...
    • Recognition of vessel acoustic signatures using non-linear teager energy based features 

      Can, Gökmen; Akbaş, Cem Emre; Çetin, A. Enis (IEEE, 2016-10)
      This paper proposes a vessel recognition and classification system based on vessel acoustic signatures. Teager Energy Operator (TEO) based Mel Frequency Cepstral Coefficients (MFCC) are used for the first time in Underwater ...
    • Teager energy based feature parameters for robust speech recognition in car noise 

      Jabloun, F.; Çetin, A. E. (IEEE, Piscataway, NJ, United States, 1999)
      In this paper, a new set of speech feature parameters based on multirate signal processing and the Teager Energy Operator is developed. The speech signal is first divided into nonuniform subbands in mel-scale using a ...
    • Wavelet domain textual coding of Ottoman script images 

      Gerek, Ömer. N.; Çetin, A. Enis; Tewfik, A. H. (SPIE, 1996-03)
      Image coding using wavelet transform, DCT, and similar transform techniques is well established. On the other hand, these coding methods neither take into account the special characteristics of the images in a database nor ...
