MORALES-MENDOZA, Luis Javier; VAZQUEZ-BAUTISTA, Rene Fabián; MORALES-MENDOZA, Efrén y SEMENOVICH SHMALIY, Yuriy. Speckle Noise Reduction in Ultrasound Imaging using the Key Points in Low Degree Unbiased FIR Filters. Comp. y Sist. [online]. 2012, vol.16, n.3, pp.287-295. ISSN 2007-9737.
In this paper we present a method of reducing speckle noise ¡n applications for ultrasound image processing using low degree unbiased FIR filters. An important feature of the p-lag gain of unbiased FIR filters is that at some cross points it converges to the reduced degree gain. The results are evaluated in terms of the signal-to-noise ratio (SNR) and the root mean square error (RMSE) metrics. We show that ultrasound image enhancing with different degree FIR filters at special lags allows getting best results depending on applications.
