…-fix Fix infinite loop on ArUco apriltag refinement * Fix infinite loop on ArUco apriltag refinement Software entered infinite loop when image height was smaller than 10*cv::getNumThreads(). With high core count machines this could happen with very reasonable image sizes. Fix is to ensure that chunksize is at least 1. * Test aruco detection with different number of threads Test ensures that different aruco detection methods do not produce different results based on number of threads. Test was created after observing infinite loop caused by small image and large number of threads when using apriltag corner refinement. * Test refactoring. * Syntax fix for pre-C++11 compilers.
