    • 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 ...

    • Idler-efficiency-enhanced long-wave infrared beam generation using aperiodic orientation-patterned GaAs gratings 

      Figen, Z. G.; Aytür, O.; Arıkan, O. (Optical Society of America, 2016)
      In this paper, we design aperiodic gratings based on orientation-patterned gallium arsenide (OP-GaAs) for converting 2.1 μm pump laser radiation into long-wave infrared (8-12 μm) in an idler-efficiency-enhanced scheme. ...

    • 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 ...

    • 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 ...

    • Teager energy based feature parameters for speech recognition in car noise 

      Jabloun, F.; Çetin, A. E.; Erzin, E. (Institute of Electrical and Electronics Engineers, 1999-10)
      In this letter, a new set of speech feature parameters based on multirate signal processing and the Teager energy operator is introduced. The speech signal is first divided into nonuniform subbands in mel-scale using a ...
