You have to overwrite the ".backgrounds" class instead ".state-background". Background images are not placed in ".slides". That's why your CSS code wont blur the background images.

.backgrounds {
     -webkit-filter: blur(5px);
     -moz-filter: blur(50px);
     -o-filter: blur(5px);
     -ms-filter: blur(5px);
     filter: blur(5px);
 }
