Abstract

The peak-and-valley filter has been shown to be a fast and efficient filter in suppressing impulsive noise. In order to find the best filtering route, we have tested several different kinds of scanning orders, such as zigzag scan, Hilbert curve, etc. The result of the tests shows the vertical scanning order is the best one. Next, we have incorporated a simple edge detection scheme into the peak-and-valley filter and then propose a new filter, called the cross-type peak-and-valley filter. Experimental results show that our filter with vertical filtering route outperforms the peak-and-valley filter proposed by Windyga.
