Besides the various answers provided under the links Chethankumar posted, I propose looking at the IMREAD/IMWRITE functions in Matlab (see links).

@Chenying Gao

Hope u mean the images are under a directory (not under a file).

If I have 4 images, namely

IMG_PM1.jpg

IMG_PM2.jpg

IMG_PM3.jpg

IMG_PM4.jpg

in a folder

'E:\personal\Photo\'

then, I can read and display all those images using the following code with a simple for loop

for i=1:4

filename = ['E:\personal\Photo\IMG_PM',num2str(i), '.jpg'];

im=imread(filename); %read the images

imtool(im);                     %display the images

end

Hope this will help you.

datapath='/Users/gaochenying1/Documents/MATLAB/roof_images_copy/';

img_dir = dir(strcat(datapath,'*.jpg'));

for frame = 1:numel(img_dir),

   img = imread(strcat(datapath,img_dir(frame).name));

end

Thank you so much! 

On a general note: As different OS use different file separators (compare Chao's "/" on Linux to Priyadarsini "\" on Windows) it is best to replace hard coded file separators by using the FULLFILE and FILESEP functions. These determine the file separator depending on the OS and thus will make your code (more) portable. In Priyadarsini's example, replace

  filename = ['E:\personal\Photo\IMG_PM',num2str(i), '.jpg'];

by

  filename = fullfile('E:','personal','Photo',sprintf('IMG_PM%d.jpg',i));

Thank u Prof David !

I work on Windows platform and had forgotten about this basic difference! Thanks a lot for your valuable input! Also thankful to Prof Chao Xing. I had never tried using the wildcard char (*) ! It further simplifies  the code  ! With *, we need not to use the for loop and even need not to have any prior info regarding total number of files present! The following code now lists all images IMG_MP*.jpg under my directory!

filename = fullfile('E:','personal', 'Photo', 'IMG_MP*.jpg');

dir(filename)

But, now I have one doubt. The output is produced as a row vector. example,

IMG_MP1.jpg IMG_MP2.jpg IMG_MP3.jpg IMG_MP4.jpg IMG_MP5.jpg

How to list the names one below another in columnar form? for example

IMG_MP1.jpg

IMG_MP2.jpg

IMG_MP3.jpg

Hey Priyadarsini!

since the DIR command displays its output on the command line if no output argument is given, you can not change that (although the command line display is formatted quite nicely). If you want to have a simple column output, my quick-and-dirty fix would be:

  S = struct2cell(dir(filename));

  disp(char(S(1,:)));

See DIR for more info on its output  argument (basically a struct with different fields; "name" contains the file names).
