Identify similarly named images from different folders

Lets say I have folder A with five images (named: '5', '2', 'pic', '4', 'photo'), and another folder B with two images (named: '4', 'pic'), all of the same format and type. I want to make a for loop which identifies the similarly named images from each folder in order to perform some analysis on them, i.e. read image '4' from each folder and do the analysis, then image 'pic' from each folder and do the analysis (order does not matter).

Thanks!

Try to make something out of this

    s1 = dir( fullfile( folder_1, '*.png' );
    s2 = dir( fullfile( folder_2, '*.png' );

    % name_list = union( {s1.name}, {s2.name} );
    name_list = intersect( {s1.name}, {s2.name} ); % thanks to @Image

    for jj = 1 : length( name_list )
        name_list{jj} 
    end

Addendum

On Windows, upper and lower case might cause problems. ABC.png is the same name as abc.png. Replace

    name_list = intersect( {s1.name}, {s2.name} );

by

    name_list = intersect( lower({s1.name}), lower({s2.name}) );

Wouldn't it be intersect() instead of union()?

Absolutely!

Worked perfectly. Thanks again!
