Does anyone have a C code for light-source-direction-estimation-from-a-single-image?

Like @Guanta said, please put some effort in it. IF you have googled for an approach, try implementing it and get back here with your suggestions and problems. Just posting a question which is basically telling us 'please solve my high school project' will not get you anywhere on this forum.

@StevenPuttemans: thanks for writing a more comprehensive statement, I was too lazy :)

Yes,it was too begging. Then, I would appreciate it if anyone could suggest where to find the algolithm so that I could implement it into C codes partly using OpenCV libraries.

I found a couple of papers where I could read a complete light-direction-estimation algorithm without communicating with each author. Though each algorithm has some strong limitations such as spherical for depicted objects, it will do as a starting point anyway, thanks.

Basically this link says it all : http://bit.ly/126QQRX

Steps to follow:

  • Click link
  • Pick a paper
  • Read the paper
  • Look for necessary techniques in C++ to build the algorithm, using google or search function

BTW looking at how recent these papers are (techniques invented in 2009-2010 are considered new in computer vision) it will be hard to find a copy paste algorithm. You will have to dig in it yourself unfortionately.
