How to get back an original image from its smoothed form applied by Gaussian smoothing filters?

I have the following image. Cameraman.tif. I have applied the following code the image.

I = imread('cameraman.tif');
Iblur1 = imgaussfilt(I,2);
figure
imshow(I)
title('Original image')
figure
imshow(Iblur1)
title('Smoothed image, \sigma = 2')

Now i need to get back the original image from the smoothed image. Can anyone please figure it out. It will be highly appreciated if you provide the relevant code.

Thanks in advance.
