Hi, I used the following code: I have two axes. In one axes i'll display the image and in the other axes i want the details of the image. Can you please help me in getting the image details in the axes or please tell me an alternate way to do that.

\\\\\

axes(handles.axes1);

[baseFileName,folder]=uigetfile('*'); % read the input image

im=imread([folder,baseFileName]);

ImageOriginal = im;

imshow(ImageOriginal);

axes(handles.axes2);

info=imfinfo(baseFileName);

info

////////////

By using this, i am getting the image details in the matlab main window but not in the GUI axes. please assist me.

thanks...

What details do you want to know? Maybe you want to use imfinfo() or impixelinfo().

info is a structure so you need to create a string with sprintf() and then send that string into the text control with set().

>> info=imfinfo('moon.tif') % Or whatever image you want.
info =
