How does detectCheckerboardPoints work?

Hi!
I am wondering how the function "detectCheckerboardPoints" works. What prerequisites are there for the image I? What algorithm is behind the function? E.g., does it rely on a harris corner detector? Does it explicitly look for quadrilaterals? Why doesn't it work for this image, for example?

Probably because it's such a poor quality image. You might have to do some preprocessing first to get rid of the noise and posterization, and of course better image capture environment (lighting, geometry, etc.).

Because if it's important enough for him, he might buy the toolbox. Why would I not refer him to an answer just because I personally don't have the toolbox that has a function I know would help him? Why should I withhold such potentially valuable and helpful information? (By the way, I have the toolbox now.)
