Edge-preserving-filter

This script is the torch implementation of the domain transform Recursive Filter described in the paper:

Domain Transform for Edge-Aware Image and Video Processing
Eduardo S. L. Gastal and Manuel M. Oliveira
ACM Transactions on Graphics. Volume 30 (2011), Number 4.
Proceedings of SIGGRAPH 2011, Article 69.

Requirements

Torch 7 [https://github.com/torch/torch7]

Arguments:

RF Domain tranform recursive edge-preserving fitler

F = RF(img, sigma_s, sigma_r, num_iterations, joint_image)

Parameters: img: input image to be filtered

sigma_s:         Filter spatial standard deviation

sigma_r:         Filter range standard deviation

num_iterations   Number of iterations to perform (defualt: 3)

joint_image      Optional image for joint filtering.
