FCNet: A feature context network based on ensemble framework for image retrieval

open access: yesIET Computer Vision, 2022
In order to train an end‐to‐end model for better performance in distinguishing superclasses and make the model more sensitive to inter‐class differences, the authors propose a Feature Context Network (FCNet), a novel ensemble framework for image ...

Deep Learning Measurement Model to Segment the Nuchal Translucency Region for the Early Identification of Down Syndrome

open access: yesMeasurement Science Review, 2022
Down syndrome (DS) or Trisomy 21 is a genetic disorder that causes intellectual and mental disability in fetuses. The most essential marker for detecting DS during the first trimester of pregnancy is nuchal translucency (NT).

Generalized convolutions V [PDF]

open access: yesStudia Mathematica, 1973
This paper is a continuation of part III, ibid. 80, 167-189 (1984; Zbl 0561.60019). It deals with generalized convolution algebras (\({\mathcal P},\circ)\), i.e. \({\mathcal P}\) is the set of all probability measures on the positive half-line and ``\(\circ ''\) is a generalized convolution of measures from \({\mathcal P}\).

ASSOCIATIVE CONVOLUTIONS ARISING FROM CONDITIONALLY FREE CONVOLUTION [PDF]

open access: yesInfinite Dimensional Analysis, Quantum Probability and Related Topics, 2005
We define two families of deformations of probability measures depending on the second free cumulants and the corresponding new associative convolutions arising from the conditionally free convolution. These deformations do not commute with dilation of measures, which means that the limit theorems cannot be obtained as a direct application of the ...

Bayes Convolution

open access: yesInternational Statistical Review / Revue Internationale de Statistique, 1999
SummaryA general convolution theorem within a Bayesian framework is presented. Consider estimation of the Euclidean parameter θ by an estimator T within a parametric model. Let W be a prior distribution for θ and define G as the W‐average of the distribution of T ‐ θ under θ.

Collocating Convolutions [PDF]

open access: yesMathematics of Computation, 1995
An explicit method is derived for collocating either of the convolution integrals p ( x ) = ∫ a x f ( x − t ) g ( t ) d t p(x) = \smallint _a^xf(x - t)g(t)dt or q (

Digital filters: hermitian, antihermitian, unitary and their applications

open access: yesTechnical Transactions, 2017
The paper presents the relation between the three types of noncausal digital filters: unitary, Hermitian and antihermitian filters. A decomposition has been made of a causal filter into a Hermitian and unitary filter cascade, and the use of this ...
