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

Monocular Visual-IMU Odometry: A Comparative Evaluation of Detector-Descriptor-Based Methods
, 2019 Monocular visual-IMU (Inertial Measurement Unit) odometry has been widely used in various intelligent vehicles. As a popular technique, detector-descriptor based visual-IMU odometry is effective and efficient due to the fact that local descriptors are ...

Descriptor standard and positive discrete-time nonlinear systems
Archives of Control Sciences, 2015 A method of analysis of descriptor nonlinear discrete-time systems with regular pencils of linear part is proposed. The method is based on the Weierstrass-Kronecker decomposition of the pencils.

Extending the sGLOH Descriptor [PDF]
, 2015 This paper proposes an extension of the sGLOH keypoint descriptor [3] which improves its robustness and discriminability. The sGLOH descriptor can handle discrete rotations by a cyclic shift of its elements thanks to its circular structure, but its performance can decrease when the keypoint relative rotation is in between two sGLOH discrete rotations ...

Descriptor-Driven de Novo Design Algorithms for DOCK6 Using RDKit
, 2023 Structure-based methods that employ principles of de novo design can be used to construct small organic molecules from scratch using pre-existing fragment libraries to sample chemical space and are an important class of computational algorithms for drug ...

Rethinking the sGLOH Descriptor
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2018 sGLOH (shifting GLOH) is a histogram-based keypoint descriptor that can be associated to multiple quantized rotations of the keypoint patch without any recomputation. This property can be exploited to define the best distance between two descriptor vectors, thus avoiding computing the dominant orientation.

Global Context Descriptors for SURF and MSER Feature Descriptors [PDF]
2010 Canadian Conference on Computer and Robot Vision, 2010 Global context descriptors are vectors of additional information appended to an existing descriptor, and are computed as a log-polar histogram of nearby curvature values. These have been proposed in the past to make Scale Invariant Feature Transform (SIFT) matching more robust. This additional information improved matching results especially for images

Assigning Main Orientation to an EOH Descriptor on Multispectral Images
Sensors, 2015 This paper proposes an approach to compute an EOH (edge-oriented histogram) descriptor with main orientation. EOH has a better matching ability than SIFT (scale-invariant feature transform) on multispectral images, but does not assign a main orientation ...
