On computing minimal realizations of periodic descriptor systems [PDF]

, 2007
: We propose computationally efficient and numerically reliable algorithms to compute minimal realizations of periodic descriptor systems. The main computational tool employed for the structural analysis of periodic descriptor systems (i.e., reachability

A Feature Descriptor by Difference of Polynomials

IPSJ Transactions on Computer Vision and Applications, 2013
In this paper, we propose a novel local image descriptor DoP which is termed as the difference of images represented by polynomials in different degrees. Once an interest point/region is extracted by a common image detec- tor such as Harris corner, our DoP descriptor is able to characterize the interest point/region with high distinctiveness ...

Anomaly Detection Based on Local Nearest Neighbor Distance Descriptor in Crowded Scenes

The Scientific World Journal, 2014
We propose a novel local nearest neighbor distance (LNND) descriptor for anomaly detection in crowded scenes. Comparing with the commonly used low-level feature descriptors in previous works, LNND descriptor has two major advantages.

An SIFT-Based Fast Image Alignment Algorithm for High-Resolution Image

IEEE Access, 2023
To solve the problem of high-resolution image alignment time overhead, an SIFT-based fast image alignment algorithm is presented. The overlap region of images is computed in detail by phase correlation algorithm to avoid a lot of useless calculations of ...

Simultaneous feature selection and parameter optimisation using an artificial ant colony : case study of melting point prediction [PDF]

, 2008
We present a novel feature selection algorithm, Winnowing Artificial Ant Colony (WAAC), that performs simultaneous feature selection and model parameter optimisation for the development of predictive quantitative structure-property relationship (QSPR ...
