Adding the composer dependency in the namespace

I have downloaded the blueimp uploader package via composer. Now I want to use the class within the laravel namespace.
The directory structure for the package is vendor\blueimp\jquery-file-upload\server\php\UploadHandler.php. It has a index.php file that invokes the class file in normal execution.
I want to call a route in my controller that will give me files uploaded by user(using Request::file) and that I would pass to the UploadHandler class,which would process the image and return the uploaded path.
