+import numpy as np
+import matplotlib.pyplot as plt
+import pycs
+
+# Generate a test image
+img = np.random.randn(256, 256)
+
+# Take the starlet transform with 5 wavelet scales
+st = pycs.astro.wl.image.transforms.starlet2d(img, nscales=5)
+
+# Compute the aperture mass map at scale 4 using the starlet filter
+apm = pycs.astro.wl.image.filters.aperture_mass(img, theta=2**4, filter='starlet')
+
+# Plot
+fig, (ax1, ax2) = plt.subplots(1, 2, figsize=(6, 5))
+ax1.imshow(st[3], cmap='magma')
+ax2.imshow(apm, cmap='magma')
