    Evaluation of Robust Covariance Estimation for Object Detection
    (Universidad EAFIT, 2021-04-07) Tamayo-Arango, Andres Felipe; Plazas Escudero, David; Vidal-Correa, Juan Pablo; Universidad EAFIT, School of Sciences, Department of Mathematical Sciences
    This work presents an initial approach to the evaluation of robust covariance estimation for object detection (localization) using the “region covariance” technique from the literature. The covariance estimation is performed using the Comedian, Kendall, Spearman and Ledoit and Wolf robust approaches for covariance, and the procedure was also compared using two different matrix norms for estimating dissimilarity. The performance was measured quantitatively using linear regression and Pareto boundaries, yielding the Ledoit and Wolf estimation with best overall performance in object detection in normal and noisy images.
