I have a folder with unknown 'n' number of image files. I want to correlate all of these images with a 'single image'obtained from another location.The name of the image from 'n' image files which has highest correlation coefficient with 'single image', should be displayed as answer. following link is very helpful but can I need to run a loop to correlate 'single image' with 'n'files from the folder and display the name, can I get help in this, thanks in advance

Thanks for your support,I have added below line to get only the name of file without ext.

[pathstr,name,ext]= fileparts(name_of_best)
disp(name)

It is displayed in command window. Now I want to display this name in static text box.I want to get this done without adding any push button i-e when above code runs it should display 'name' in static text box not anything else.

Alternatively, If possible to create a function to pick 'name' from the above code in static text, can I get help for this.
