EdgePreserving-Blur

This program creates beautiful blurred images while preserving the edges, texture and details in them.
Basically, it's a c++ implementation of Edge-preserving multiscale image decomposition based on local extrema by Subr, Kartic, Cyril Soler, and Frédo Durand. ACM Transactions on Graphics (TOG) 28.5 (2009): 147.
