WebHigher-order statistics The proposed methods are based upon the third-order cumulant s; their main properties are quickly recalled. ... The noise-cancellation property of the third-order cumulant s implies that equation (1) is (asymptotically) noise-free, consequently the simple least-squares method gi ves consistant estimates. However, when only a Web1. Introduction and Review It is well known that cumulants of order greater than two are zero for random variables which are Gaussian. In view of this, higher order cumulants are …

WebJun 1, 2024 · In order to improve the system's ability to extract targets, a high-order cumulant detection algorithm based on motion direction estimation is proposed. The aim of this algorithm is to enhance the signal of weak targets by estimating the motion direction of targets between frames, and then accumulating multiple frames along the direction of ...
