Aort valve Doppler signal noise elimination using IIR filter designed with ABC algorithm
Koza T.; Karabo?a N.; Koçkanat S. (International Symposium on INnovations in Intelligent SysTems and Applications, INISTA 2012, 2012)The heart valves are most important parts of the heart. The biomedical signals such as aortic valve Doppler signals are sensitive to noise and interference. In this paper, aortic valve Doppler noise is eliminated with an ... -
Examination of success of the finite impulse response digital filter designed using the bat algorithm [Yarasa algoritmasinin sonlu dürtü tepkili sayisal süzgeç tasarimindaki başariminin incelenmesi]
Logoglu A.; Koza T.; Kockanat S.; Karaboga N. (Institute of Electrical and Electronics Engineers Inc., 2018)This paper represents, a new heuristic algorithm, bat algorithm, is used to optimize filter coefficients in the design of low pass finite impulse response (FIR) digital filter. The FIR digital filters have a wide range of ... -
Image denoising with 2-D FIR filter by using artificial bee colony algorithm
Kockanat S.; Karaboga N.; Koza T. (International Symposium on INnovations in Intelligent SysTems and Applications, INISTA 2012, 2012)In this paper, a new design approach that has employed the artificial bee colony algorithm for image denoising using two dimensional finite impulse response digital filter, is discussed. Four different images have been ... -
Noise cancellation application of ECG signal using artificial bee colony algorithm [Yapay Ari Koloni Algoritmasi Kullanilarak EKG Işaretinin Gürültü Giderimi Uygulamasi]
Kockanat S.; Koza T.; Karaboga N.; Erkoc M.E. (24th Signal Processing and Communication Application Conference, SIU 2016, 2016)Electrocardiographic (ECG) signal is a biological signal that contains useful information about electrical activities of hearth. When obtaining ECG signals by using electronic equipment, there can be many distortions in ...
