Tutorial/CorrelationImageVelocimetryOptimisation
v17 v18 38 38 Now come back to the default value 10, and press the button '''[!TestPatch1]'''. This will perform patch calculations with a range of values for the smoothing parameters, and provide the rms difference between the filtered velocity field and the initial Civ1 field. This ranges from 0.12, '''[!FieldSmooth]'''=1, to more than 0.2 for '''[!FieldSmooth]'''=100. The value 0.15 for '''[!FieldSmooth]'''=10 is less that the expected error on the PIV, about 0.2 pixel. 39 39 40 41 [[Image(41.png)]] 40 42 **Figure: GUI civ_input + graphe obtenu par !!TestPatch. 41 43
