The paper presents a novel, theoretically well-based methodology to find changes in remote sensing image series. The proposed method finds changes in images scanned with a long time-interval difference in very different lighting and surface conditions. The presented method is basically an exploitation of the Harris saliency function and its derivatives for finding featuring points among image s...

In this paper, we investigate interpolatory projection framework for model reduction of descriptor systems. With a simple numerical example, we first illustrate that employing subspace conditions from the standard state space settings to descriptor systems generically leads to unbounded H2 or H∞ errors due to the mismatch of the polynomial parts of the full and reducedorder transfer functions. ...

In this paper, we present a new approach to investigate the existence and design of reduced-order proper H∞ controllers that provide the same level of performance as that of full-order controllers. By examining some special features of the LMI-based solvability conditions for the H∞ control problem for descriptor systems, we obtain a refined bound on the order of H∞ controllers, which is indepe...
