Matofpoint2f operator

WebSo turning back to your particular question, to create a MatOfPoint2f containing the points corresponding to ones from existing MatOfKeyPoint you need: iterate through KeyPoint [] and create a corresponding Point [] (all of cv::Point, cv::Point2f and cv::Point2d are represented as org.opencv.core.Point in Java) Thank you very much! Web13 aug. 2024 · You simply need to apply the concept of non maxima suppression on your data. That means that for every contour, find other contours that at least overlap 50%. Replace both by their intersection over union for example. Its standard in any detection algorithm. StevenPuttemans (Aug 14 '17) edit.
