I think you can implement using css! please check out
http://www.w3schools.com/svg/svg_fegaussianblur.asp
You can use alot of different filters by declaring them like
<filter id="f1" x="0" y="0">
<feGaussianBlur in="SourceGraphic" stdDeviation="15" />
</filter>
these can be black and white filters, cyanotype etc. From there just reference it on the object using filter='url(#f1)'
EDIT
CAN BE DONE USING BLUR CSS
