checkerboard_level_set(shape, square_size=5)#

Return a binary checkerboard level‑set the same shape as shape.

compute_force(abs_du, image, c0, c1, lambda1, lambda2)#

Return the geodesic force term.

compute_means(image, mask)#

Compute mean intensity outside/inside the mask.

morphological_chan_vese(image, shape, num_iter, lambda1=1.0, lambda2=1.0)#

Segment image using MorphACWE.

Parameters:

  • image (ndarray[float32] (Z, Y, X)) – 3‑D scalar field to segment. Values should be scaled 0‑1.

  • num_iter (int) – Number of iterations.

  • lambda1 (float) – Chan–Vese region weight parameters.

  • lambda2 (float) – Chan–Vese region weight parameters.

update_curve(u, aux)#

Binary threshold update of the level‑set function.
