pfs-calibration is a set of command line tools for reconstructing an HDR image from a sequence of exposured. The software implements two photometric calibration methods: by Robertson et al. 2003 and by Mitsunaga and Nayar 1999. pfs-calibration is a part of pfstools (from version 2.0).

Here are some key features:

Tools provided with this software can be used for photometric calibration of both off-the-shelf digital cameras and HDR cameras as described in:

Check a short tutorial on calibration of the LDR cameras and the recovery of the HDR images from multiple exposures. For details on the calibration of the HDR cameras please refer to the research report.

Please refer to the original pfscalibration web page for more information.


pfstools 2.0.5 releasedThu, 26 May 2016 09:41:02 -0000

This is a bug fix release, addressing issues in Octave interface, newer compilers and with some HDR file formats.

pfstools 2.0.3 releasedTue, 28 Apr 2015 15:53:37 -0000

This is a minor release, which fixes several important issues, including a bug in pfshdrcalibration, storing 32-bit EXR files and improvements in cmake build scripts.

pfstools 2.0.2 releasedSun, 15 Mar 2015 13:01:47 -0000

pfstools 2.0.2 is a minor release, which fixes several issues in the cmake files and in the documentation.

pfstools 2.0.1 releasedSat, 07 Feb 2015 10:47:27 -0000

This version contains two major changes as compared with 1.9.x: 1) pfstools now include all "tools" from pfstmo and pfscalibration in one package so there is no need to install and compile them separately, which should save time; and 2) the build system has been changed from automake to cmake. This should make it easier to compile pfstools on different platforms.

This version adds also a new tone-mapping operator (mai11) and a number of bug fixes and minor improvements. Refer to the change log below.

2.0.1 is a minor release, which adds a new tone-mapping operator - pfstmo_ferradans11.
