在 MATLAB Online 中打开

After going through the code. It seems to be imprinting random artifacts on to the image

A = imread('dataset/1.jpg');%original image
G = double(A);
G(rand(size(G))<0.50) = NaN;
Gnan = G;
figure
image(uint8(Gnan))
title 'Corrupted - 50%'

I achieved this by just extracting this code from their program. However is there a way to add text instead of NaN?
