The width and transparency of the selection can be modified in order to create a thick, thin, heavy, or light blur.

I want it to kinda blend in so to say here is the pic. html   The selective Gaussian blur filter was applied to several human classification datasets to order to enhance the quality of edge-based features for image classification.
