This software package generates high-dynamic range environment map from a single image by using an approach described in the following paper: J.-F. Lalonde, A. A. Efros, and S. G. Narasimhan. Webcam clip art: Appearance and illuminant transfer from time-lapse sequences. ACM Transactions on Graphics (SIGGRAPH Asia 2009), 28(5), December 2009. Please cite this paper if you use this code in your work. See 'demoEnvMapGeneration.m' as a starting point on how to use the software, which should be self-explanatory. Let me know if you have questions. *** REQUIRED 3RD-PARTY SOFTWARE NOT INCLUDED WITH THIS PACKAGE *** - the 'parseargs' matlab function by Malcolm Wood available at: http://www.mathworks.com/matlabcentral/fileexchange/10670-parseargs-simplifies-input-processing-for-functions-with-multiple-options *** REQUIRED SOFTWARE NOT INCLUDED WITH THIS PACKAGE *** - environment map conversion routines, available at http://www.cs.cmu.edu/~jlalonde/software.html#envMapConversions - sky model code, available at http://www.cs.cmu.edu/~jlalonde/software.html#skyModel *** NOTES *** The cloud synthesis step described in the paper is not currently available as the original implementation used a version of the Image Quilting code which is not publically available. One should be able to find freely-available implementations online, however.
