to download the Trilateral Filter algorithm implementation for Tone mapping that uses pfstools.This is an implementation of Choudhuary's Trilateral Filter [7] algorithm. This is an implementation of Choudhury’s Trilateral Filter [10] algorithm. The development started by experimenting with the code supplied with the DVD of the book by Erik Reinhard [2]. You need to have cygwin [4] in windows to run this code. This code requires pfstools. This is an addition to PFSTMO implemented algorithms. There are 5 files in this implementation: tmo_trilateral.cpp, pfstmo_trilateral.cpp, tmo_trilateral.h, lum.h, and memory.h

There are 5 files in this implementation: tmo_trilateral.cpp, pfstmo_trilateral.cpp, tmo_trilateral.h, lum.h, and memory.h.
The following optional parameters are present.
* @brief trilateral filter tone-mapping
*
* @param Y input luminance
* @param L output tonemapped intensities
* @param contrast:- c (default : 5.0)
* @param sigma:- g (default : 21.0)
* @param shift:- t (default: 0.0)
* @param saturation:- s (default: 1.0)
* @verbose:-v
* @help:-h
The following command in cygwin illustrates the use:
