How to visualize a 3D Nifti image as a slider in Python

You can visualize a 3D Nifti image as a slider in Python. If you want to learn about computer vision, I strongly advise you to read This book.

Step 1: Install the NiBabel library

pip install nibabel

Step 2: Visualize a 3D Nifti image as a slider

# Import the required modules
import nibabel as nib
from ipywidgets import interact
from matplotlib import pyplot as plt

# Load the Nifti File
image = nib.load('data.nii')

# Convert the image data as a NumPy array
array = image.get_fdata()

# Visualize Images as a slider
def show_slice(i):
    plt.imshow(array[:,:,i], cmap='gray')
    plt.show()

interact(show_slice, i=(0, array.shape[2]-1))
