Before Change

ax[0, 2].imshow(denoise_bilateral(noisy, sigma_color=0.05, sigma_spatial=15))
ax[0, 2].axis("off")
ax[0, 2].set_title("Bilateral")
ax[0, 3].imshow(denoise_wavelet(noisy, sigma=0.4*astro.std(),
                                multichannel=True))
ax[0, 3].axis("off")
ax[0, 3].set_title("Wavelet")

After Change

sigma_est = estimate_sigma(noisy, multichannel=True, average_sigmas=True)
// Due to clipping in random_noise, the estimate will be a bit smaller than the
// specified sigma.
print("Estimated Gaussian noise standard deviation = {}".format(sigma_est))

ax[0, 0].imshow(noisy)
ax[0, 0].axis("off")
