create set of set of images listed in a file.

HI,

i am a beginner student in MATLAB i want to know how can i create file to store a set of (JPEG format)images as i want to load this images from this file in MATLAB

This is possible with TIFF, MAT, GIF, AVI and a much more formats. Please post, what you exactly want by editing the question, not by adding a comment.

What kind of file should the end result be?

[Image Analyst]

They're already in files, though separate files, not one file with hundreds of images in it. Maybe she means how to read a file into a MATLAB variable. If so, use imread(). If she needs to write a MATLAB variable into a file on disk, use imwrite().

@Walter Roberson i want to make external file that store a set of images and then load this images in matlab

[Walter Roberson]

Are you asking for a .mat file? For an SQL database? For DICOM? Are the images all the same size and you are trying to create a volume?

I am not sure why you are creating a file to store the images? Why not just load the images in MATLAB ?

[Image Analyst]

Especially since she already has the images in jpeg files. Why create another file when you already have files? Losy, can you answer that?

[Jan]

A useful answer requires, that out questions have been cleared at first.

[losy]

yes that is i need , i need to store group of images in a file that store them or in SQL database if it possible to connect matlab with SQL please help me

[Image Analyst]

Well which one is it? Surely you must have a preference because those are drastically different things. For saving to an image file I already asked you to look at the TIFF class - see the help.

[Walter Roberson]

If you can explain why you need to store them in a file before doing the PCA, instead of just loading them at the time of doing the PCA, then we could possibly recommend an approach.

Look at the TIFF class. I think (though I've never done it) that it can save multiple images into one file.
