Why titles are flipped vertically in the following code?

%Please change the file formats into tif first
clear;
clc;
close all;
I=imread('Fig0316(1)(top_left).tif');
I1=imread('Fig0316(2)(2nd_from_top).tif');
I2=imread('Fig0316(3)(third_from_top).tif');
I3=imread('Fig0316(4)(bottom_left).tif');
[nk, rk]=imhist(I);
[nk1, rk1]=imhist(I1);
[nk2, rk2]=imhist(I2);
[nk3, rk3]=imhist(I3);
figure('Name','Images with different contrast','NumberTitle','off');
subplot(2,4,1)
imshow(I);
title('Brighter Image');
subplot(2,4,2)
imshow(I1);
title('Low Contrast Image');
subplot(2,4,3)
imshow(I2);
title('High Contrast Image');
subplot(2,4,4)
imshow(I3);
title('Darker Image');
subplot(2,4,5)
bar(rk,nk);
title('histogram for Brigher Image');
subplot(2,4,6)
bar(rk1,nk1);
title('histogram for Low Contrast Image');
subplot(2,4,7)
bar(rk2,nk2);
title('histogram for High Contrast Image');
subplot(2,4,8)
bar(rk3,nk3);
title('histogram for Darker Image');

Thanks.

Also upload your image files

Not flipped for me. What version of MATLAB are you using? Could you upload an image of what you are seeing in your figure?

[soe]

I'm using MATLAB R2013a.

Here is like that.

'imhist' requires Image Processing Toolbox.

Error in Untitled3 (line 8)

[nk, rk]=imhist(I);

How to resolve this error

Answer 1

[Cris LaPierre]

That's weird. It's not a common issue - it'd be all over the place if it were. After some searching, I found this post saying there can be issues with some ATI graphics cards. Try the suggestions there (updating graphics drivers, switching renderer) and let us know if that solved the problem.

Thank you so much!

opengl('software') command has solved my problem!
