%Program To Read, Wirte and Display an Image





clear all;

close all;

clc;

I = imread('cameraman.tif');

[I1,map] = imread('trees.tif');

[I2,map] = imread('forest.tif');


%TO CONVERT ONE IMAGE FORMAT INTO ANOTHER FORMAT [(i.e.) from tif image to jpeg](OR) TO WRITE THE DATA IN AN IMAGE


imwrite(I,'cameraman.jpeg');

imwrite(I1,map,'trees.jpeg');

imwrite(I2,map,'forest.jpeg');


%TO READ AN IMAGE

J = imread('cameraman.jpeg');

K = imread('trees.jpeg');

M = imread('forest.jpeg');


%TO FIND OUT THE SIZE OF THE IMAGE

size(J)

size(K)

size(M)

disp('If the size is 2D Matrix it is a gray scale image');

disp('If the size is 3D Matrix it is a color image');


%TO DISPLAY AN IMAGE

figure(1)

imshow(J)

figure(2)

imshow(K)

figure(3)

imshow(M)




TUTOTIAL 2

%TO FIND OUT THE PIXEL VALUE OF AN IMAGE

TUTOTIAL 3

%TO GET ALL INFORMATION ABOUT AN IMAGE

%SUCH AS

%(1) File size

% (2) Number of Bits used to represent a pixel

% (3) Resoultion

% (4) Gray (or) Binary (or) Color Image

% (5) Width and Height

% (6) Maximum Pixel value

% (6) Image format such as TIFF (or) JPEG
