Yes circular markers should be better especially if combined with other methods, which unfortunately are not implemented in opencv. See e.g. paper by Datta, Kim, Kanade.

2013-09-16 12:43:07 -0600	asked a question	c2039 VS2012 build erros While compiling the master from github (eff21788a80738db8b0a5901c21e447ff9134d96) on VS2012 (ultimate) under Windows 8 in 32bit mode, I get the following error(s) in Debug mode: C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\include\xutility(364): error C2039: 'iterator_category' : is not a member of 'cv::MatIterator_<_Tp>' In Release mode the error does not appear. Is it a bug?

2013-04-15 13:28:09 -0600	asked a question	tests fail depending on compiler: is it OK? Compiled git version of opencv with intel and clang compilers. Many tests fail if compiled with intel compiler. Eg. ./opencv_perf_features2d typical failed test lools like `The difference between expect_min and actual_min is 7.2759576141834259e-12, which exceeds eps, where expect_min evaluates to 7.5574986112769693e-05, actual_min evaluates to 7.5574993388727307e-05, and eps evaluates to 2.2204460492503131e-16. Argument "points-response" has unexpected minimal value` Is it known or expected behaviour?
