Connected Component Manipulation

The Brainlit package contains some functions to manipulate connected components. This is usually done on binary images, especially labels.

import numpy as np
from brainlit.preprocessing import getLargestCC, removeSmallCCs
from skimage import data
import matplotlib.pyplot as plt

img = data.binary_blobs(512, 0.1, n_dim=2, volume_fraction=0.5, seed=10)
largest_cc = getLargestCC(img)
large_cc = removeSmallCCs(img, 10000)


plt.figure()
plt.subplot(1, 3, 1)
plt.imshow(img)
plt.title("Original Image")
plt.axis("Off")
plt.subplot(1, 3, 2)
plt.imshow(largest_cc)
plt.title("Largest CC")
plt.axis("Off")
plt.subplot(1, 3, 3)
plt.imshow(large_cc)
plt.title("Small CCs Removed")
plt.axis("Off")
plt.show()
