Algorithm {Maximum matching of selected points in the interval}
Algorithm {Maximum matching of selected points in the interval} Maximum matching of selected points in the interval Definition Given an interval set A (each interval [l,r] is an integer), you need to select a point set P from the real number domain so that there is a subset SA of A, satisfying: There is a […]
Two-dimensional feature framework – AKAZE local feature matching OpenCV v4.8.0
Previous tutorial: Detecting Planar Objects Next tutorial: AKAZE and ORB planar tracking Original author Fedor Morozov Compatibility OpenCV >= 3.0 Introduction In this tutorial, we will learn how to use AKAZE[10] local features to detect and match keypoints on two images. We will find keypoints on a pair of images given an isomorphism matrix, match […]

07 | switch matching: can it adapt to different types?
The pattern matching feature of switch is released as a preview in JDK 17. According to the usual schedule, this feature may require another two or three versions before it is finalized. This feature is very simple, but very important and can help us solve many difficult and important problems. We might as well try […]
