It is shown that, features obtained via shrunk covariance estimation are suitable for describing trajectories. Compared to Dynamic Time Warping, application of explained technique is faster and yields more accurate results. An improvement of Dynamic Time Warping based on counting statistical comparison of base distance measures is also achieved. Results on Australian Sign Language and Character Trajectories datasets are reported. Experiment realizations imply feasibility through covariance attributes on time series.eninfo:eu-repo/semantics/openAccessCovariance MatricesData MiningSign LanguageTime Series AnalysisArticle243788110.5755/j01.eie.24.3.15290
