batch-selective-blur

;; Batch processes all files within the current directory 
;; by running a selective blur on each image and then saving them
;; WARNING: edits the original file. Run this on copies of the original images.

;; Example execution: 
;; gimp -i -b '(batch-selective-blur "*.jpg" 6.0 31)' -b '(gimp-quit 0)'
