python-scipyHow can I use Python and SciPy to apply a Gaussian filter?

Using Python and SciPy, a Gaussian filter can be applied to an image. To do this, the scipy.ndimage.filters.gaussian_filter function can be used. For example, the following code will apply a Gaussian filter to an image, where img is the image array and sigma is the standard deviation for the Gaussian kernel:

from scipy.ndimage.filters import gaussian_filter
filtered_img = gaussian_filter(img, sigma=sigma)

The parts of the code are as follows:

• from scipy.ndimage.filters import gaussian_filter imports the gaussian_filter function from SciPy.
• gaussian_filter(img, sigma=sigma) applies the Gaussian filter to the image array img with standard deviation sigma.
• filtered_img is the filtered image array.
