distance between two groups of centroids

[jackyko1991]

I am following this guide to measure the distance between two spare cell types: https://github.com/clEsperanto/pyclesperanto_prototype/blob/master/demo/neighbors/distance_to_other_labels.ipynb

This works fine but I am trying to repeat the method with distance matrix to their centroids

# generate distance matrix
distance_matrix = cle.generate_distance_matrix(cen_A, cen_B)

TCell count: 294
CancerCell count: 691

Give the distance matrix as follows:

Then I try to filter out the long distance cells with connection matrix:

connection_matrix = cle.smaller_or_equal_constant(distance_matrix, constant=10)

But seems the function touch_matrix_to_mesh is not designed for this type of mesh, but only works within in same label group

mesh = cle.create_like(imageA)
cle.touch_matrix_to_mesh(cen_A, connection_matrix, mesh)
fig, ax = plt.subplots(1,1,figsize=(15,15))
ax.set_axis_off()
ax.imshow(exposure.rescale_intensity(imageA, in_range=(pl, pu),out_range=(0,255)),cmap='Greens',alpha=0.7)
ax.imshow(exposure.rescale_intensity(imageB, in_range=(pl, pu),out_range=(0,255)),cmap='Reds',alpha=0.7)
cle.imshow(mesh, labels=True, plot=ax, alpha=0.5)

Is there some workaround for the task?
