问题
dose anybody know why is cv::findChessboardCorners horribly slow on all images with more than one mega-pixel ( > 1 000 000 pixles ).
As a workaround I down-sample my images to fit this bound, but I would like to know if it can be solved more "elegantly".
Thanx

Haven't dug into the reasons - I wrote a much faster square finder from scratch.
The circleGrid provides a better result and is much faster, it uses the new BlobDetector interface.
