Algorithms based on direct calculation of two covariance matrices for all source images without converting them into vectors. Evaluated characteristics of the presented algorithms. We discuss possibilities presented by the use of algorithms in other areas. AU - N. Shchegoleva AU - Georgy Kukharev UR - https://bijournal.hse.ru/en/2011--4/44326814.html PY - 2011 SP - 31-38 VL -
