Class ThresholdMedianSmoother

java.lang.Object

skyview.process.Processor

skyview.data.ThresholdMedianSmoother

All Implemented Interfaces:

java.io.Serializable, Component

public class ThresholdMedianSmoother
extends Processor

Do a median smoothing for all pixels that differ from the median by more then the threshold Settings used: MedianSmoother=size[,threshold] Size gives the size of the box in which the median is computed This must be an odd integer >= 3 Threshold is the change beyond which the pixel will be smoothed Assumed to be 0 if omitted which means that all pixels are smoothed. RatioThreshold If specified then the threshold will be computed as a ratio of the current and median values. E.g., if specified and threshold is 2 then Pixels <0.5 or >2.0 times the median value will be smoothed. SingleSided=(+|-) If specified should have the single character values + or - which indicates that only only values greater than or less than the median will be considered for smoothing.
