APPARATUS FOR FORMING FLOW-MAP IMAGES USING TWO-DIMENSIONAL SPATIAL FILTERS

摘要

The appts. derivs. from data values located at the intersections of coordinates derive. a display data value to be used at an intersection near or at the middle of the intersections. The numbers of each coordinate need not be equal. If an odd number of each type of coordinate are used the chosen one of the selected data values can be displayed at the intersection of the centre coordinates of each type. If an even number of each type of coordinates is used, the chosen selected data value can be displayed at any one of the four intersections of the two innermost coordinates of each type.
