Thanks to Daniel A. da Silva (PhD student at Universidade de Blumenau, Brazil), you can now pre-process your hemispherical images using Python code instead of Matlab. Daniel translated the code for us. Credits along with Daniel’s contact e-mail can be found in the introduction of the code.

I tried uploading as file to the blog, but unfortunately python codes are not allowed. For feedback: write to us or Daniel. Thank you.
