Hi Putra,

You can use the following code to load files into matlab. Keep the image files and and .m file in same directory.

A = imread('owl.0.jpg');
B = imread('owl.1.jpg');
C = imread('owl.2.jpg');

You can refer to this documentation for more info Read image from graphics file

@Manas

I tried imread and save it in one .mat file, but i want all 3 images have the same name.

just like this 3 picture format, which in the same name "I"

Hi Putra,

In the "I' file, 65536 x 3, here '3' is for the RGB values, it doesn't signify that is has 3 different images stored in it. If you really want all the .jpg files in same matrix, then you can use the following code

A = imread('owl.0.jpg');
B = imread('owl.1.jpg');
C = imread('owl.2.jpg');
I = [A B C];

Hi Putra, Actually here we can use imread function:

img1=imread('owl.0.jpg');
img2=imread('owl.1.jpg');
img3=imread('owl.2.jpg');

Now as you want to concatenate the matrix , we can do the same as follows:

IMG1 = [img1 img2 img3] %340 x 1536 x 3
%or 
IMG=[img1;img2;img3] % 1020 x 512 x 3

Here you can access individual images as follows:

img1=IMG(1);
img2=IMT(2);
img3=IMG(3);
