Hello everybody !
Currently I am facing task of creating application that solves camera position from different projections. This process rely heavily on solving minimal solution of n x m matrix where m (height) > n (width). This solution is obtained by calculating SVD. Currently I am not properly educated in this area therefore I am not sure if it is a good idea to start implementing it on my own. Could anybody provide some pseudo code ore any kind of guideline that would lead me so that it wont take more time than necessary ? Other choice is to use some external functions. I don't want my application to by installation dependent just jet , so if somebody could provide library that could be included in project it would be very appreciated. I am working on windows form application , c++. Thanks in advance.

these link are helpful in understanding SVD concept

hopes this helps, I also want to implement this. Not getting time :(

Great documents, thank you very much , however I am going to leave this topic unanswered cause I am still hoping for some advice covering external libraries.

i think OpenCV has class for finding SVD.
see http://opencv.willowgarage.com/documentation/cpp/core_operations_on_arrays.html#SVD

good luck

yes but that would require user to have some opencl release installed and I really don't want that.
