Abstract:Besides 2-D filtering etc,median filtering can also be used to separate upgoing waves from downgoing waves in VSP data processing How the method is performed is outlined, its behaviour and basic theory are also expounded, Median filtering is essentially a median method, Median filtering is different from the generally used least square method because it determines parameters on condition that the sum of absolute value errors is minimized.
