A Generalized Loss Function for Crowd Counting and Localization [PDF]
, 2021 Previous work [40] shows that a better density map representation can improve the performance of crowd counting. In this paper, we investigate learning the density map representation through an unbalanced optimal transport problem, and propose a ...

Comparative growth of an entire function and the integrated counting function of its zeros
Carpathian Mathematical PublicationsLet $(\zeta_n)$ be a sequence of complex numbers such that $\zeta_n\to\infty$ as $n\to\infty$, $N(r)$ be the integrated counting function of this sequence, and let $\alpha$ be a positive continuous and increasing to $+\infty$ function on $\mathbb{R}$ for which $\alpha(r)=o(\log (N(r)/\log r))$ as $r\to+\infty$. It is proved that for any set $E\subset(1,

Physica MedicaWhen evaluating the task transfer function (TTF) of monoenergetic (MonoE) CT applying energy-domain noise reduction (EDNR), special caution should be exercised on the task size because of the low-pass filtering (LPF) process involved. The purpose of this study was to evaluate TTFs at MonoE at 40 keV compared with those at polyenergy (PolyE) at 120 kV.A

The Fractal Nature of an Approximate Prime Counting Function
Fractal and Fractional, 2017 Prime number related fractal polygons and curves are derived by combining two different aspects. One is an approximation of the prime counting function build on an additive function.

The expressibility of functions on the Boolean domain, with applications to Counting CSPs [PDF]
, 2013 An important tool in the study of the complexity of Constraint Satisfaction Problems (CSPs) is the notion of a relational clone, which is the set of all relations expressible using primitive positive formulas over a particular set of base relations. Post'

Chebysev’s Estimate of the Prime Counting Function
, 2020 In this article we shall discuss about Chebyshev’s estimates of the prime counting function, which was later superseded by the Prime Number Theorem, nonetheless it is significant from both mathematical and historical perspective. Chebyshev’s estimates of

Rice Seedling Counting in Complex Environments Based on Domain-Adaptive NWD-YOLOv5 [PDF]
Jisuanji gongchengComplex environments, such as green algae, that interfere with the counting of microscopic rice seedlings are often encountered in the early stages of rice cultivation, making it difficult to distinguish microscopic rice seedlings from the background ...
