WebMar 11, 2024 · In this post, we will learn how to perform feature-based image alignment using OpenCV. We will share code in both C++ and Python. We will demonstrate the steps by way of an example in which we will align a photo of a form taken using a mobile phone to a template of the form. The technique we will use is often called “feature based” image ... WebMay 10, 2024 · The reason is the number of inliers is used as criteria for calculating homography transformation matrix H. “However, for high-resolution images, it’s common that you’ll actually find false matches with a considerable number of inliers, as long as enough RANSAC iterations are performed.”[5] Thus, after each matrix estimation, we …
