Overview

Implementation of the Non-Local Means (NLM) and the Gaussian filter with OpenMPI in a distributed processing cluster with one master and two slave nodes

Dependencies

• GNU Make 4.1
• stb - for image manipulation

How to use

Non-Local Means Filter

make nlm w=3 sw=5 sigma=2.5 imgs="img1 img2 img3 etc"

make nlm-mpi w=3 sm=5 sigma=2.5 imgs="img1 img2 img3 etc"

Gaussian Filter

make gaussian w=5 sigma=1.5 imgs="img1 img2 img3 etc"

make gaussian-mpi w=5 sigma=1.5 imgs="img1 img2 img3 etc"
