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-1))
