Web13 apr. 2024 · You can fit an ellipse over a shape using the fitEllipse () method of the org.opencv.imgproc.Imgproc class. This method accepts an object of MatOfPoint2f class, calculates the ellipse that would fit the given set of points and returns a RotatedRect object. Using this you can draw ellipses around the possible objects in an image. Web20 sep. 2024 · Contours.

Web31 jul. 2024 · 1. Hello. I've got a next problem: I'm trying to load trained SVM, but I'm getting crush. I trained my SVM, using C++ and OpenCV 3.2.0. Aftr that I've put the results to the .yml file. Then I copy this .yml file to the root of the StreamingAssets folder. When start I'm searching for this file and then put trained SVM to my SVM object.
