Abstract: In this paper, we propose an approach for anomaly detection in crowded scenes. For this purpose, two important types of features that encode motion and appearance cues are combined with the help of covariance matrix. Covariance matrices are symmetric positive definite (SPD) matrices which lie in the Riemannian manifold and are not suitable for Euclidean operations. To make covariance matrices suitable for use in the Euclidean space, they are converted to log-Euclidean covariance matrices (LECM) by using log-Euclidean framework. Then LECM features created in two different ways are used with one-class SVM to detect abnormal events. Experiments carried out on an anomaly detection benchmark dataset and comparison made with previous studies show that successful results are obtained.
