Flying Small Target Detection for Anti-UAV Based on a Gaussian Mixture Model in a Compressive Sensing Domain

Sensors, 2019
Addressing the problems of visual surveillance for anti-UAV, a new flying small target detection method is proposed based on Gaussian mixture background modeling in a compressive sensing domain and low-rank and sparse matrix decomposition of local image.

Preconditioners for domain decomposition methods

Computers & Mathematics with Applications, 2001
For solving nonsymmetric linear system, the Schur domain decomposition method proposes a dual approach of the Schur formulation. One constraint of this method is that its condition number increases with the amount of subdomains. In this paper, a family of parallel global preconditioners, which can alleviate the above constraint, are presented.

Real Wages and the Business Cycle in Germany [PDF]

This paper establishes stylized facts about the cyclicality of real consumer wages and real producer wages in Germany. As detrending methods we apply the deterministic trend model, the Beveridge-Nelson decomposition, the Hodrick-Prescott filter, the ...

A Learning-Based Domain Decomposition Method

Recent developments in mechanical, aerospace, and structural engineering have driven a growing need for efficient ways to model and analyse structures at much larger and more complex scales than before. While established numerical methods like the Finite Element Method remain reliable, they often struggle with computational cost and scalability when ...
