The theme is not entirely reflects the essence, apply a blur easily, almost any library for image is able to do, you need to look for how to recognize a "causal space" in this picture where in consequence it is necessary to impose a blur.

imagemagick or something like that. - you can use it to overlay one image on another. One can be the original, the other blue/something similar
