images.internal.getImageFromFile expects the input argument to be string (the filename for the image). But it is something else. That is what the error means.

How did you get into this error please? Did you call montage with some inputs?

could you help me? i have tried many times

this my code :

img = imread('00187.jpg');

imgGray = rgb2gray(imread('00187.jpg'));

imshow(imgGray);

BW = imbinarize(imgGray);

imshow(BW);

montage({imgGray, BW});

this is error:

The specified filename is not a string.
