Tutorial/AdvancedParticleImagingVelocimetry
v15 v16 42 42 43 43 == Profiles == 44 44 The velocity profile along a line can be obtained by creating a line with the upper menu bar '''[Projection object/line]'''. Then press the left hand side mouse button and draw the line, keeping the button pressed. Release the button to stop the drawing. The transverse and longitudinal velocity components along this line are then plotted in a new figure '''view_field'''. 45 45 46 46 == Histograms == 47 47 The global histograms of the displayed quantities (vector components or image brightness) are available in the lower left windows. Histograms limited to a sub-region can be extracted by the menu bar tool '''[Projection object]''', selecting either ['''rectangle]''', '''[ellipse]''' or '''[polygon]''' to define the sub-region. Then draw the contour with the mouse, like for line profiles.
