Module Contents

drop.improcessing.worthington.worthington(edges, calib, surface_tension, fluid_density, gravity=None)

Compute the worthington number.

Parameters:

edges : boolean image

Image containing the edges to fit.

calib : scalar

Calibration scale in m/px.

surface_tension : scalar

Surface tension in N/m.

fluid_density : scalar,

Fluid density in kg/m3.

gravity : scalar, optional

Gravitational acceleration. If None, scipy.constants.g is used.

Returns:

worthington : scalar
