can any one please help me with this coad

function varargout = gui(varargin)
% GUI M-file for gui.fig
%      GUI, by itself, creates a new GUI or raises the existing
%      singleton*.
%
%      H = GUI returns the handle to a new GUI or the handle to
%      the existing singleton*.
%
%      GUI('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in GUI.M with the given input arguments.
%
%      GUI('Property','Value',...) creates a new GUI or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before gui_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to gui_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".

Answer 1

[SRI]

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

[nihaar u]

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?
