% GUI M-file for gui.fig
% GUI, by itself, creates a new GUI or raises the existing

% H = GUI returns the handle to a new GUI or the handle to
% the existing singleton*.

for example you can try this
InputImage = imread('peppers.png');
imshow(InputImage)
it results you a image with size 256*256*3
first thing repersent row then col, then dimension..
if you want a gray image means
please use this
Outimage = rgb2gray('InputImage)
imshow(Outimage)
this result you gray image which has size of 256*256 represents only row and col
If you are satisfied then accept my answer

when i use imsize('ex image'); it shows somw 1 20 ( for color) for a gray scale image also it shows some 1 15 if i read and store for ex- a=imread('gray scale image.jpg'); >> size(a) ans =
200 200 3
then
b=imread('(rgb) color image.jpg');
>> size(b)
ans =
307 450 3
how does matlab know its rgb i.e color or an gray scale image
in my code it says if p=3 then rgb2 gray so what is p and where is it displayed when i read and display size?
