Enhancing low-light images is crucial for various applications in computer vision, yet current approaches often fall short in balancing image quality and detail preservation. This study introduces a novel method designed to enhance low-light images by applying advanced mathematical techniques from geometric function theory. Specifically, we employ...
Pollen allergies, also known as hay fever or allergic rhinitis, impact millions of people worldwide, especially during peak seasons when pollen concentrations in the air are elevated. Traditional methods of monitoring pollen levels, such as manual counting and analysis of pollen traps, often result in delayed reports that do not provide real-time d...
The aim of this research is to enhance image quality by applying convolution methods to a newly generalized subclass of an analytic function, \(k-\Omega S^*(\rho ,\beta )\), which incorporates the concept of the Mittag-Leffer type Poisson distribution associated with starlike functions. Image enhancement processes, such as noise reduction, sharpeni...
This Proposed work explores how machine learning can be used to diagnose conjunctivitis, a common eye ailment. The main goal of the study is to capture eye images using camera-based systems, perform image pre-processing, and employ image segmentation techniques, particularly the UNet++ and U-net models. Additionally, the study involves extracting f...
This research introduces a new approach to elevate the precision of image edge detection through
a new algorithm rooted in the coefficients derived from the subclass 𝑡,𝜌 (CSKP model). Our

Few subclasses of Sakaguchi type functions are introduced in this arti-cle, based on the notion of Mittag-Leffler type Poisson distribution series. The classp-ΦS∗(t, μ, ν, J, K) is defined, and the necessary and sufficient condition, convex combina-tion, growth distortion bounds, and partial sums are discussed.
The identification of illnesses relating to the retina is greatly aided by retinal fundus imaging. Retinal image enhancement typically aids in the analysis of disorders connected to the retinal fundus image because the detailed information of the retinal fundus image, such as small vessels, microaneurysms and exudates, may be in low contrast. The f...
Digital image processing has a wide range of uses, including robotics and automated inspection of industrial parts. Other uses include remote sensing using satellites and other spacecraft, image transmission and storage for business applications, medical processing, and Acoustic image processing. The process of highlighting particular intriguing fe...
Abstract This present work provides the initial co-efficient bounds of the function f(z) which is defined in open unit disk $$\mathbb {D}$$ D . We introduced bi-univalent class $$\mathcal {C}_{\Sigma }(\lambda , t,\nu )$$ C Σ ( λ , t , ν ) . Making use of Horadam polynomials $$h_{n}(\nu )$$ h n ( ν ) and the generating function $$\Pi (\nu ,z)$$ Π (...
The objective of the paper is to study the geometrical properties of the class B(λ, t). For which we have proved that the radius √ 3−u3 3 is optimal ,(i.e) the number √ 3−u3 3 cannot be replaced by a larger one. Additionally, the graphs for various values of t and λ are compared in order to study the sharpness of the coefficient bounds.

From these functions we obtain the bounds of first four coefficients, and then we have derived the Toeplitz determinant T 2 (2) and T 3 (1) whose diagonal entr...

Furthermore for functions in each of the subclasses introduced in this paper, we obtain the initial coefficient bound for| am+ 1| and| a2m+ 1|.

An analytic function is quasi-subordinate to an analytic function, in the open unit disk if there exist analytic function and, with(0)= 0 and 1 such that subclasses of analytic univalent functions associated with quasi-subordination are defined and the bounds for the Fekete-Szego coefficient functional for functions belonging to these subclasses ar...
