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.
Java convert MatOfPoint in MatOfPoint2f - OpenCV Q&A Forum
Web21 sep. 2024 · The Python and C++ API documentation of OpenCV seems to be much more thorough but there are some things that aren't inclusive to the Java and this C# API (like the MatOfPoint2f class example I gave), so it kind of bothers me that I have to look at the code that I wanted abstracted away in order to understand how to use it. WebWe then convert the lists of points to MatOfPoint2f as follows: org.opencv.core.Point goodPointArray1 [] = new org.opencv.core.Point [goodKeyPoints1.size ()]; … hawaii things to do 2022
