Regular filter for vector maps 
Edpiv pE 2013 — help 
Dialogue box “Regular filter for vector maps” allows you to set Filter type  Median filter: Local median value is used to validate current vector;  Lowpass filter: Replace current vector with the local mean vector;  Highpass filter: Subtract the local mean vector from current vector. Filter mask radius  Rx : Horizontal radius, i.e. width of the filter mask is 2Rx+1;  Ry : Vertical radius, i.e. height of the filter mask is 2Ry+1;  Rt : Temporal radius, i.e. number of related vector maps is 2Rt+1. Limits for error detection [pixel]  dx : Limit of horizontal displacement variation;  dy : Limit of vertical displacement variation;  dz : Limit of outoffplane displacement variation. Buttons  Temporal button : Shortcut button for temporal filter, i.e. Rx=0, Ry=0, Rt=”total number of vector maps”;  Spatial button : Shortcut button for 3X3 filters, i.e. Rx=1, Ry1, Rt=0;  3D filter : Shortcut button for 3X3X3 filters, i.e. Rx=1, Ry1, Rt=1.  OK button : Conduct filter operation and close the dialogue Box;  Cancel button : Close the dialogue Box without conducting filter operation.
