Abstract
A new class of nonlinear filters which combines the thresholding operation with a median or mean filter is introduced. A simple but robust method to generate thresholds is proposed. Based on it, the new filters are analyzed for their white noise attenuation and abilities to eliminate impulse noise and preserve edges. Results are compared to those of the median, FIR median hybrid (FMH), and mean filters, showing several advantages of the new filters
