Parameter could be exposed in the ORB constructor enabling user to set it based on their dynamic range. History Alexander Shishkov on 2013-02-28 13:24 - Category set to features2d Mark Stevens on 2013-02-28 14:17 cv::gpu::ORB_GPU has the following function: inline void setFastParams(int threshold, bool nonmaxSupression = true) { fastDetector_.threshold = threshold; fastDetector_.nonmaxSupression = nonmaxSupression; } which would provide required functionality. —Reply to this email directly or view it on GitHub.
