An earlier approach to corner detection is to detect points where the curvature of level curves and the gradient magnitude are simultaneously high. A differential way to detect such points is by computing the rescaled level curve curvature (the product of the level curve curvature and the gradient magnitude raised to the power of three) and to detect positive maxima and negative minima of this differential expression at some scale in … WebDec 21, 2024 · As I discussed in last week’s tutorial, the OpenCV library comes with built-in ArUco support, both for generating ArUco markers and for detecting them.
