About

pfs calibration package provides an implementation of the Robertson et al. 2003 and Mitsunaga and Nayar 1999 methods for the photometric calibration of cameras and for the recovery of high dynamic range (HDR) images from the set of low dynamic range (LDR) exposures.

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. These pages will be extended in the future.

News

This realease brings an updated "pfsview", which is now 100% QT4
application. Some cosmetic problems as well as "Fit window to content"
have been fixed. Other minor fixes are listed below.

This release of pfscalibration fixes many issues with handling RAW (more than 8-bit) images. Robertson's algorithm should produce less banding. Mitsunaga and Nayar's algorithm is still broken. Two new scripts have been added: pfsinme - to skip generating an intermediate hdrgen file; and pfsplotresponse - for plotting camera response functions.

This release fixes several bugs in pfsview, hdrhtml, and pfsinppm. You may also appreciate much better OS X support and updated README.OSX. The compilation on Mac has been tested with Fink and native qt3-mac.

Probably the most interesting addition is an HDRHTML viewer for displaying HDR images with exposure control in a web-browser (http://pfstools.sourceforge.net/hdrhtml). Matlab functions can now read and write multi-channel images, and have updated documentation (http://pfstools.sourceforge.net/matlab_docs/index.html). Other changes:
