Affine Invariant OpenCV Descriptors and the Effects on Aerial Photogrammetry
Evan O’Keeffe, Debra F. Laefer, Eleni Mangina
Abstract. Robust feature descriptors are necessary for computer vision applications such as image matching, photogrammetric three-dimensional (3D) reconstructions, and simultaneous localisation and mapping (SLAM). While most state-of-the-art feature descriptors are invariant to i…
