Fusion of block and keypoints based approaches for effective copy-move image forgery detectionMultidimensional Systems and Signal Processing - Tập 27 - Trang 989-1005 - 2016
Jiangbin Zheng, Yanan Liu, Jinchang Ren, Tingge Zhu, Yijun Yan, Heng Yang
Keypoint-based and block-based methods are two main categories of techniques for
detecting copy-move forged images, one of the most common digital image forgery
schemes. In general, block-based methods suffer from high computational cost due
to the large number of image blocks used and fail to handle geometric
transformations. On the contrary, keypoint-based approaches can overcome these
two drawb... hiện toàn bộ

Triangular representation of Fornasini–Marchesini systemsMultidimensional Systems and Signal Processing - Tập 20 - Trang 217-234 - 2008
Chen Dubi
We further develop the study of Fornasini–Marchesini linear systems with upper
triangular state operators, addressing the problem of constructing a triangular
Fornasini–Marchesini model equivalent (under a proper definition) to a given
system. In particular, we are interested in the problem of determining when such
a system can be constructed, without losing the information about the state of
the ... hiện toàn bộ
On Stability Robustness of 2-D Systems Described by the Fornasini–Marchesini ModelMultidimensional Systems and Signal Processing - Tập 12 - Trang 81-88 - 2001
Tatsushi Ooba
This paper studies the stability robustness estimates of two-dimensional(2-D)
dynamics in the Fornasini–Marchesini model. It isstressed that the use of 2-D
Lyapunov matrix inequality is limitedin application to the stability robustness
estimate problem.Two alternative ways to estimate the stability robustness ofa
2-D dynamics are proposed. These are applicable in any stable2-D dynamics. The

A Stochastic Analysis of Performance Limits for Optical MicroscopesMultidimensional Systems and Signal Processing - Tập 17 - Trang 27-57 - 2006
Sripad Ram, E. Sally Ward, Raimund J. Ober
The optical microscope is a powerful instrument for observing cellular events.
Recently, the increased use of microscopy in quantitative biological research,
including single molecule microscopy, has generated significant interest in
determining the performance limits of an optical microscope. Here, we formulate
this problem in the context of a parameter estimation approach in which the
acquired i... hiện toàn bộ
Recursive partial realization for 2-D data arraysMultidimensional Systems and Signal Processing - Tập 2 - Trang 101-126 - 1991
Sandro Zampieri
In this paper an attempt is made to provide a proper formalization to the
partial realization problem for discrete linear causal shift invariant 2-D
systems. The approach falls into the class of 2-D Padé approximations; the
results, however, are new, since the rational representation matches all the
samples of a 2-D partial sequence. The realization algorithm, though
characterized by a high comple... hiện toàn bộ
