Thank you Thomas.

I have 1 more problem.

http://matlab.wikia.com/wiki/FAQ#How_can_I_process_a_sequence_of_files.3F

According to that link, how i can input (only my image name) in array ?

so the output will be like this :

array(1,1) = apple

array(2,1) = banana

array(3,1) = watermelon

....

array(n,1) = nfriuts

thank you.

BR,

You could try

name={'apple','banana','mango'}; % put this before the loop

for k=1:....

jpgFilename = strcat(name(k), '.jpg');

end

What is "one execution"? You'll need to call imread() 10 times - once for each image. You'll need to change the filename for each call, which it looks like you'll have to do manually since your filenames don't depend on any loop index or anything like that (unless you want to make a cell array or use a cell array like you get from dir()). I recommend just putting the 10 calls to imread directly into your code and I don't recommend using a loop unless the exact filenames are not known in advance, like you need to call dir() to retrieve them or something. If that is the case, the see the FAQ like Thomas pointed you to.

So is 10 calls to imread in one single m file "one execution" according to your definition? I hope so because that's pretty much the only way to do it.

Thank you Image Analyst.

How i can save 'baseFileName' in array ?

[Image Analyst]

baseFileName{k} = jpegFiles(k).name; % Note: {k}, not (k) on the LHS
