time_of_flight#

time_of_flight(image, boundary='l', detrend=True)[source]#

Compute time of flight map (solution to Eikonal equation) from specified boundary (inlet or outlet) Assumes img = 1 in pore space, 0 for grain space Assumes flow is in z direction (orthogonal to axis 2)

Return type:

ndarray

Parameters:
  • image – An np.ndarray containing the binary image with the phase of interest labeled as 1

  • boundary – Left (‘l’) or right (‘r’) boundaries corresponding to the inlet or outlet

  • detrend – If detrend is True, then subtract the solution assuming no solid matrix is present in the image.

  • masked. (The solid matrix is still)

Returns:

Time of flight map from specified boundary

Return type:

numpy.ndarray
