Abstract :
In this paper we give an analysis of special points of the noise power gain of p-lag median hybrid FIR filters in applications to image processing. An important feature of the p-lag gain is that, at some cross points, it converges to the reduced degree one. The results are evaluated in terms of the signal-to-noise ratio (SNR) and root mean square error (RMSE) metrics. We show that image enhancing with different degree FIR filters at special lags allows getting best results depending on applications.
