Methods for Determining the Size of three-Dimensional Objects in Images
Цифровая трансформация, 2021 Computer vision technology is used to obtain the necessary information from images. The two-dimensional image was transformed into its corresponding three-dimensional structure based on the reconstruction process and singular points. A review of software

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 ...

Tools for Fast Metric Data Search in Structural Methods for Image Classification
IEEE Access, 2022 The article proposes a new classification method based on implementing the high-speed search tools for the indexed data structure created on the etalon set of features, which has significant advantages in processing speed compared to the traditional ...

Component evolution analysis in descriptor graphs for descriptor ranking [PDF]
Digital Signal Processing, 2014 Abstract This paper presents a method based on graph behaviour analysis for the evaluation of descriptor graphs (applied to image/video datasets) for descriptor performance analysis and ranking. Starting from the Erdős–Renyi model on uniform random graphs, the paper presents results of investigating random geometric graph behaviour in relation with ...

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

Positivity of Continuous-Time Descriptor Systems With Time Delays [PDF]
, 2014 This technical note is concerned with positivity characteristic of continuous-time descriptor systems with time delays. First, a set of necessary and sufficient conditions is presented to check the property.

Descriptor Revision for Conditionals: Literal Descriptors and Conditional Preservation [PDF]
, 2020 Descriptor revision by Hansson is a framework for addressing the problem of belief change. In descriptor revision, different kinds of change processes are dealt with in a joint framework. Individual change requirements are qualified by specific success conditions expressed by a belief descriptor, and belief descriptors can be combined by logical ...

Bounded real lemmas for positive descriptor systems [PDF]
, 2015 A well known result in the theory of linear positive systems is the existence of positive definite diagonal matrix (PDDM) solutions to some well known linear matrix inequalities (LMIs).
