.. _generic_corner_detector: Creating yor own corner detector ******************************** Goal ===== In this tutorial you will learn how to: .. container:: enumeratevisibleitemswithsquare * Use the OpenCV function :corner_eigenvals_and_vecs:`cornerEigenValsAndVecs <>` to find the eigenvalues and eigenvectors to determine if a pixel is a corner. * Use the OpenCV function :corner_min_eigenval:`cornerMinEigenVal <>` to find the minimum eigenvalues for corner detection. * To implement our own version of the Harris detector as well as the Shi-Tomasi detector, by using the two functions above.
