WebFeb 26, 2016 · 11. I am trying to detect elliptical kernels, in OpenCV using C++. I have tried obtaining Canny edges, and then using fitEllipse () function on the edges. Though this finds ellipses, the accuracy is horrid when the image is noisy, or if there are many edges. I have realised that the way to go is detecting ellipses, and not fitting them.

WebUse an algebraic fit for this purpose. We recommend Taubin fit. Kasa fit (the simplest and fastest fit, but biased toward smaller circles when an incomplete arc is observed) Pratt fit (more robust than Kasa fit, but a little slower) Taubin fit (similar to Pratt fit, but a bit faster and a bit more accurate) (perhaps the best algebraic circle fit) WebApr 4, 2024 · 起初想到做这个是因为项目里有几个发光字要识别，而Halcon自带的OCR里面没有找到汉字的分类器，所以想着自己训练一下，这样可以更有针对性。做为一个肤浅的初学者，学halcon也是个逐步摸索的过程，感谢老乡Z提供的入门资料，这里记录下实验过程。
