Pub Date : 2023-01-01 DOI: 10.46253/j.mr.v6i4.a3
: Pest, Plant disease, climate change, and disaster are the major factor to determine the yeild of the plant. Pest inthe plants are identified in different methods. To process the images with machine vision models’ the quality of images isan important concern. Noise and unwanted artifacts integrated with the images at the time of acquisition and transmission. Noise is introduced in the images due to transmission, environment distortion, and sensor qualities. In this regard, some solutions related to the post-image-acquisition are required to enhance such issues. In this, image denoiser plays an important role to enhance the quality and minimize the noises in images. However, to preserve details of images a comparative analysis of related image denoising algorithms is conducted. In this study, the authors cover three types of filters to minimize the noise of insect pests’ images to find better ones. The experiment of the comparative study revealed that the Total Variation (TV) algorithm gives better results as compared to another denoising algorithm at different noise levels.

Pub Date : 2023-01-01 DOI: 10.46253/j.mr.v6i4.a2
: The study explores the application of telemedicine in healthcare delivery in Nigeria, the perception of medical practitioners, and its application in healthcare service delivery to the nation. An architectural framework was designed to depict the application of healthcare delivery via telemedicine. A questionnaire was set up to check the views of medical practitioners regarding the application of telemedicine in healthcare delivery. Over 100 questionnaires were given out to Medical practitioners, Patients, ICT providers, and Healthcare professionals who are policymakers. 95 questionnaires were returned and the remaining 5 could not be accounted for by the respondents. An evaluation was conducted on the collated data to check the ease of usage, Degree of relevance, and Reliability index of the application of telemedicine to evaluation performance metrics. 87.37% of the respondents preferred the application of telemedicine in healthcare delivery in terms of patient health management and satisfaction improvement. 12.63% of others preferred face-to-face opinions in terms of practice satisfaction to patients, Ease of use, Equipment setup expenses, Technical reliability, Time duration, Trust among the professionals, Diagnostic accuracy, and Patient convenience. The SRI, SDR, and SEU results obtained from the responses are 3.33, 3.02, and 2.65 respectively. The hypothesis derivative crouch coefficient ranges between 0.71 and 0.80 based on the validity and reliability of the application of telemedicine in healthcare delivery. Most medical practitioners were overwhelmed and supported the application of telemedicine and its application in healthcare practice. This study shows that medical practitioners are ready and prepared to accept telemedicine applications to improve healthcare delivery in Nigeria.

: Education is part and parcel of every human being. Education empowers an induvial, concocts a community, and protrudes a nation. To be educated, a person must gain knowledge through reading, listening, speaking, and writing. These processes are carried out through our body parts. Body parts such as the brain, heart, eyes, ears, mouth, hands, etc., play an important role in education. When any such body parts get affected, it will affect the entire system. Those people need extra guidance and support. As such, visually impaired students cannot read question papers during the examination as their sense of vision is deformed which can cause a lot of difficulties during their exam period including diverting the attention of the examiner to get special consideration or attention. However, a screen reading application can help impaired students to be independent in writing the exam. This project aims to address this problem by developing an Android application that has the capability of reading out questions to visually impaired students during examinations. To make the students independent in the examination hall in terms of perceiving questions. Moreover, the application can only work on mobile devices supported by the Android operating system. The Application`s reading capability is limited to questions written inEnglishlanguageonlyanditcannotreadtablesnordescribefigures.Inthecourseofthesoftwaredevelopment, this project has adhered to software Engineering principles where an iterative model was chosen as the SDLC approach to be used for the system development. After the system was fully implemented, a Beta version of the application was subjected to testing where informative feedback was obtained from testers and necessary changes were affected.

The Role of Agricultural Input Credit on Production of Maize: A Case Study in Shebedneo District, Sidama Region, Ethiopia 农业投入信贷对玉米生产的作用:以埃塞俄比亚西达马州Shebedneo地区为例
Pub Date : 2023-01-01 DOI: 10.46253/j.mr.v6i4.a4
: Smallholder farmers’ inability to procure agricultural input is one of the main causes of low agricultural productivity and production. But in recent years, the government and NGOs have tried their level best to access credits to farmers both in cash and agricultural inputs, especially fertilizers. In this study, an attempt is made to examine the role of agricultural input credit on the production of maize from a single-visit survey of the case study in Shebedino District, Sidama Region, Ethiopia. More than ever, the study tried to find out the sources of input credit for rural farmers. The major problems that hinder the use, repayment, provision, and collection of input credit for farmers and from farmers. The importance of input credit on maize production and the trends in input credit provision and repayment in Shebedino District. Hence, primary data was collected from 91 farm households drawn from three kebeles using purposive and simple random sampling. Secondary data was collected from the Shebedino District agricultural and OMO microfinance offices and different written documents. The data was analyzed using both the descriptive and econometric analysis methods. OLS models were employed to examine the role of agricultural input credit in the production of maize. The survey findings showed that there is a direct relationship between agricultural input credit and maize output performance. Loan provision in Shebedino District was increasing but the rate was not regular through the years and the repayment rate in the district was decreasing through the years. The finding also showed that educational level and savings have a positive or direct relationship with the usage and repayment of input credit among the farmers. As the findings revealed, the problems that can affect the provision and collection of agricultural inputs credit or taking and repaying the loan are low agricultural productivity, low infrastructural faculties, and low extension service. low saving and attitude of rural farmers towards the input credit service for these, providing more extensional services and infrastructural facilities side by side with credit service to rural farmers is better for increasing their productivity and it is also better if more educated people invest in agricultural activity and increase saving behavior among rural farmers to increase their income and country development.

Satellite imaging is a current development in image processing; however, it faces a lot of challenges because of the environmental factors. For denoising, state-of-the-art method has developed some filters like the hyperspectral satellite images, which is not effectual. Moreover, this paper proposed an adaptive filter using the assist of an optimization approach for the satellite image denoising. The developed adaptive filter performs the image denoising via noise correction, noise identification, and image enhancement. In the satellite image by transforming the image to a binary image, the type-2 fuzzy filter recognizes the noisy pixels which are passed via the adaptive non-local mean filter for the noise correction. Subsequently, the kernel-based interpolation scheme performs the image enhancement, which is performed through the developed improved Pigeon optimization algorithm (IPOA). The whole experimentation of the developed denoising system is performed taking into consideration by satellite images from standard databases. It is obvious that the developed adaptive filter with the developed improved Pigeon optimization algorithm has enhanced performance with the PSNR values from the outcomes.

The crowd emotion recognition is a motivating research area that helps the security personals by means of the public emotions to interpret the crowd activity in a region. Approximately several conventional techniques exploit the lowlevel visual features to comprehend the behaviors of a crowd which widen the gap between the high as well as the low-level features. The objective model is used to expand the automatic algorithm for emotion recognition; hence this work uses the Recurrent Neural Network (RNN). The Bhattacharya distance is used for effectual emotion recognition, which is necessary to choose video keyframes. The keyframes are subjected to the Space-Time Interest Points (STI) descriptor which extracts features that structure input vector to the classifier. RNN is trained by exploiting the enhanced Butterfly Optimization Algorithm (Enhanced-BOA). The developed classifier identifies the crowd emotions, like Escape, Angry, Happy, Fight, Running/Walking, Normal, as well as Violence. The experimentation of the developed technique revealed that developed technique obtained a maximum accuracy, sensitivity as well as specificity, correspondingly.

: Nowadays to secure the privacy of the patient has increased more research interest during the Image steganography process. Least Significant Bit (LSB) substitute approach was widely exploited to hide the sensitive information in the conventional works. Here, each pixel was reinstated to achieve advanced privacy, other than it increased the complexity. This paper develops a new pixel prediction model-based image steganography to surmount the complication problems widespread in the conventional works. In the proposed pixel prediction model, the K-Nearest Neighbour (KNN) classifier is used to construct the prediction map that recognizes the appropriate pixels for the embedding process. Subsequently, from the medical image to extract the wavelet coefficients based on the Discrete Wavelet Transform (DWT) and embedding power and the undisclosed message is embedded into the HL wavelet band in the embedding phase. At last, from the medical image, the concealed message is extracted by using the DWT. The simulation of the proposed pixel prediction model is carried out by exploiting medical images from the BRATS database. The proposed pixel prediction model has attained maximum performance for the Peak Signal to Noise Ratio (PSNR), Structural Similarity Index (SSIM), and correlation factor, correspondingly.
为了保护患者的隐私,在图像隐写过程中越来越受到人们的关注。最小有效位(Least Significant Bit, LSB)替代方法被广泛地用于隐藏传统工程中的敏感信息。在这里,每个像素都被恢复,以实现高级隐私,但它增加了复杂性。针对传统图像隐写工作中存在的复杂问题,提出了一种基于像素预测模型的图像隐写方法。在提出的像素预测模型中,使用k -最近邻(KNN)分类器构建预测图,识别适合嵌入过程的像素。随后,从医学图像中提取基于离散小波变换(DWT)和嵌入功率的小波系数,并在嵌入阶段将未公开信息嵌入到HL小波带中。最后,利用小波变换从医学图像中提取隐藏信息。利用BRATS数据库中的医学图像对所提出的像素预测模型进行了仿真。所提出的像素预测模型在峰值信噪比(PSNR)、结构相似度指数(SSIM)和相关因子方面达到了最佳性能。

This work uses a novel brain tumor classification technique which comprises 5 steps like “(i) denoising, (ii) skull stripping, (iii) segmentation, (iv) feature extraction and (v) classification”. At first, the image is given in the denoising procedure, whereas the amputation of the noise process is performed by using an entropy-oriented trilateral filter. Subsequently, noise removed image is used to skull stripping procedure through morphology segmentation and Otsu thresholding. Then, the segmentation takes place using the adaptive CLFAHE method. GLCM features are extracted after finishing segmentation. Here, hybrid classification represents the hybridization of 2 classifiers such as FNN and “Bayesian regularization classifier”. The very important involvement lies in the best selecting of hidden neurons in FNN. In this paper, a novel genetic algorithm based GWO (GA-GWO) method is proposed that hybrids the conception. At last, the proposed method performance is evaluated with conventional techniques to show the supremacy of the proposed method.
这项工作采用了一种新的脑肿瘤分类技术,包括5个步骤,即“(i)去噪,(ii)颅骨剥离,(iii)分割,(iv)特征提取和(v)分类”。首先,在去噪过程中给出图像,然后使用面向熵的三边滤波器对噪声过程进行截断。随后,通过形态学分割和Otsu阈值分割,将去噪图像用于颅骨剥离处理。然后,使用自适应CLFAHE方法进行分割。分割完成后提取GLCM特征。这里的混合分类是指FNN和“贝叶斯正则化分类器”等2种分类器的杂交。在FNN中,隐藏神经元的最佳选择是一个非常重要的问题。本文提出了一种新的基于遗传算法的GWO (GA-GWO)混合概念方法。最后,用常规方法对所提方法的性能进行了评价,证明了所提方法的优越性。

Pub Date : 2020-01-15 DOI: 10.46253/j.mr.v3i1.a2
: Owing to the merits of container practice such as easier and more rapid consumption, superior portability, and limited overheads, it can be extensively installed over the cloud architecture. Then, a suitable architecture solution is proposed to develop the applications, which are produced using the microservice expansion model. Thus far, numerous research works have determined on resolving the open problems in container management and automation. In reality, for cloud providers, container resource allocation is considered as the main knothole as it directly influences the system performance and resource utilization. In this way, this work initiates a novel optimized container resource allocation framework by developing a novel optimization theory. Here, a novel hybrid approach is proposed such as, SA and MFO that is the hybridization of Simulated Annealing (SA) and Moth Flame Optimization Algorithm (MFOA) to create the prospect of optimal container resource allocation. In addition, the solution of optimized resource allocation is inclined with the modeling of a novel objective model which contemplates system failure, threshold distance, total network distance, and balanced cluster use, correspondingly. At last, the performance of the proposed approach is evaluated over other existing approaches and exhibits the performance of the proposed model.
由于容器实践的优点,例如更容易和更快速的使用、优越的可移植性和有限的开销,它可以广泛地安装在云架构上。然后,提出了一种合适的体系结构方案来开发应用程序,并使用微服务扩展模型生成了应用程序。迄今为止,大量的研究工作都致力于解决集装箱管理和自动化中的开放性问题。实际上,对于云提供商来说,容器资源分配被认为是一个主要的问题,因为它直接影响到系统的性能和资源利用率。通过这种方式,本工作通过发展一种新的优化理论,启动了一种新的优化容器资源分配框架。本文将模拟退火算法(SA)和蛾焰优化算法(MFOA)相结合,提出了一种新的混合方法,即SA和MFO,为集装箱资源的最优分配创造了前景。此外,优化资源分配的解决方案倾向于建立一个新的目标模型,该模型相应考虑了系统故障、阈值距离、总网络距离和均衡集群使用。最后,对所提方法的性能进行了比较,并展示了所提模型的性能。
