Opencv shape distance and matching

Web6 de abr. de 2024 · Just want to point out that you don't need to match only contours and in fact the original paper dealt with non-binary images. Also the original paper proposes a very different distance calculation IIRC and J. Flusser et al have since proven in 90's and 06 papers IIRC that Hu's invariants are neither truly invariant nor complete. WebTemplate Matching. Prev Tutorial: Back Projection Next Tutorial: Finding contours in your image Goal. In this tutorial you will learn how to: Use the OpenCV function matchTemplate() to search for matches between an image patch and an input image; Use the OpenCV function minMaxLoc() to find the maximum and minimum values (as well as their …
