Hi all,

I am trying to understand the math behind this function and how it is implemented in Matlab, does anybody know anything about that?

Thanks, Paulo.

Refer page no: 312 this book: http://cvrs.whu.edu.cn/downloads/ebooks/Multiple%20View%20Geometry%20in%20Computer%20Vision%20(Second%20Edition).pdf

When ever you read the documentation of a function in MATLAB.....reference is also mentioned.

Hi KSSV, thanks for the answer, I already checked the book, however at this section a couple of methods is presented, I'd like to know which one is related to this Matlab's command.

I have the same problem as Paulo. The MATLAB reference does not distinguish whether MATLAB uses the homog vs. inhomog solution decribed in Hartley & Zisserman. They have substantially different properties for certain applications.
