What algorithm is used for the cornerSubPix function?

Hi everyone,

I would like a bit more information on the algorithm used by the cornerSubPix function than the official documentation provides here.

For e.g. most Camera Calibration functions/algorithms, a paper is cited that describes each algorithm in detail. Is there something like that for the cornerSubPix function?

The reason behind this is that I would like to use the Foerstner operator to achieve sub pix corner accuracy. Is there already an implementation for this algorithm (maybe in an unofficial openCV version)?

Thanks a lot! Nils
