When this technique is applied to a color image, each RGB component is processed independently and the color image is reconstructed from the outputs obtained for each component. In this case, the hue of the resultant image is significantly different from that of the input image. In addition, when the sharpening parameter is large, clipping processing is required for the output pixel values that exceed the displayable color gamut, which may cause a loss of detailed patterns. To address these problems in image sharpening, this study proposes a hue-preserving unsharp masking method with adjustable saturation. The proposed method first applies an unsharp masking technique with logarithmic ratio operations to each RGB component of the input image to obtain a sharpened image with a reduced loss of detailed patterns. The sharpened image is then approximated by a linear transformation that satisfies a conditional equation for hue preservation in the RGB color space. If the approximated pixel values are out of gamut, they are modified to be in their corresponding equi-hue planes of the RGB color space while preserving the lightness values of the sharpened image. The effectiveness and validity of the proposed method are demonstrated by comparing it with previous methods using various images. Specifically, the proposed method outperformed the comparison methods in ARNIQA, the latest non-reference image quality assessment, with a value of 0.5539. Furthermore, detailed quantitative evaluation indices such as hue preservation (HD), sharpening effect (GRVE), ratio of black and white skips (CR), and saturation index (CN) were comparable to those of the other methods.</div></div>","PeriodicalId":100554,"journal":{"name":"Franklin Open","volume":"11 ","pages":"Article 100280"},"PeriodicalIF":0.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144185655","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, interleaved boost converters, while suitable for such applications, face challenges in balancing complexity, scalability, cost, and dynamic environmental variability. This study introduces a series of novel intelligent control frameworks to overcome these limitations and improve overall system performance. Firstly, a Neuro-LSTM BitterSec Optimization Network (NL-BSONet) is proposed to enhance the efficiency of high-voltage gain interleaved boost converters while minimizing system complexity. This hybrid approach leverages neural networks and LSTM-based learning for real-time optimization, offering improved scalability and lower switching losses. To address power quality issues caused by fluctuating irradiance and wind speeds, the study introduces the Adaptive Neuro-Deep Reinforcement Learning Bitterling Optimizer (AN-DRLBO). This model integrates Deep Reinforcement Learning (DRL) for adaptive energy conversion, Adaptive Neural Networks (ANN) for real-time system stabilization, and Bitterling Fish Optimization (BFO) for robust performance under transient conditions. Furthermore, due to the difficulty in achieving optimal control parameters under variable environmental conditions, an Adaptive LSTM-Encoded Secretary Optimization Network (AL-SONet) is developed. This framework employs Long Short-Term Memory (LSTM) networks for predictive control, Autoencoder-based Optimization (AEO) for feature extraction and simplification, and Secretary Bird Optimization (SBO) for dynamic parameter tuning. The proposed architectures demonstrate superior performance, achieving 97 % energy conversion efficiency, a voltage gain of 32.5 dB, and minimal output ripple, thereby ensuring stable and efficient integration of renewable energy sources.

While current Evolutionary Mating Algorithms (EMA) primarily focus on single-objective optimization and rely on weighted functions for handling multiple objectives, such approaches prove impractical for the complex trade-offs between comfort index and energy efficiency. The proposed MOEMA enhances the original EMA framework through two key innovations: an improved crowding distance function inspired by the Non-dominated Sorting Genetic Algorithm (NSGA) to enhance solution diversity and selection pressure, and the integration of Levy flight mechanics to improve exploration efficiency by balancing local and global searches. These enhancements enable MOEMA to effectively navigate complex multi-objective landscapes, leading to more diverse and well-converged Pareto-optimal solutions. The algorithm's performance is thoroughly assessed using the chosen benchmark functions and validated through practical applications in smart building environments. It simultaneously optimizes various comfort parameters, including temperature, illuminance, and air quality, while minimizing energy consumption and maximizing the comfort index. Comparative analysis against established algorithms, like NSGA-II demonstrates MOEMA's effectiveness in achieving superior solution diversity and convergence characteristics. The results indicate that MOEMA offers a robust framework for handling the complex balance between the smart building's comfort index and energy usage where it achieves 0.03 % better at comfort index and with 10.65 % lower energy consumption than NSGA-II.

In this study, we presented a mathematical model of typhoid fever that incorporates antibiotic resistance and the implementation of antibiotic switching as a control strategy.
