MATLAB: Error in double command code

Question

Hi,

i have created a code using double command. However, there is no error. Nevertheless, the image did not appear.

the command:

————————–

Im1 = rgb2gray(image1);
I1 = double(Im1);
axes(handles.axes2);
imshow(I1);

Pls HELP.

Answer 1

Use

imshow(I1, [])

or, better yet, instead of using

I1 = double(Im1);

use

I1 = im2double(Im1);
