http://www.vision.deis.unibo.it/SHOT/ Splet12. apr. 2024 · Signature of Histogram of Orientation (SHOT) (Thomas et al. 2010c) can be considered as a combination of signatures and histograms. First, a repeatable LRF with disambiguation and uniqueness is computed for the feature point based on disambiguated eigenvalue decomposition of the covariance matrix of points within the support region.
