The emergence of Machine Learning (ML) technologies and their integration into agriculture has demonstrated a significant impact on disease detection in crops, enabling continuous monitoring and enhancing risk planning and management. This study applied image processing techniques such as thresholding, gamma correction, and the Stretched Neighborhood Effect Color to Grayscale (SNECG) method, alongside ML, to develop a predictive model for identifying five types of rice diseases. The ML techniques used included Logistic Regression, Multilayer Perceptron, Support Vector Machines, Decision Trees, and Random Forests (RF). Hyperparameters were optimized and evaluated through 5-fold cross-validation. In the results, the SNECG method successfully converted images to grayscale, capturing essential features of lesions on rice leaves. The ML models developed with these techniques showed evaluation...

Digital Image processing has been a research area of interest in the last decades, standing out for its applications in the analysis of diagnostic images and astronomical images. In this paper, we perform an overview of edge detection methods through finite-difference to present edge detection as a problem-based learning strategy for numerical differentiation, in order to improve the students’ skills in modeling and algorithmic thinking in numerical analysis courses. In addition, we present image restoration through finite-difference as a problem involving partial differential equations and software tools.

Permanent technological training favors teaching and its importance in learning modalities. Therefore, it is proposed to analyze the academic performance of permanent training in ICT skills for teachers and compare the performance of digital learning modalities. The research was quantitative, descriptive, cross-sectional in a higher education institution with continuous training processes. Two editions of courses were considered in which online TIC tools were taught for teachers. The activity records made it possible to analyze the academic performance of permanent training in TIC skills for teachers and compare the learning modalities' performance through them. In this sense, the results of the teaching-learning process in TIC skills reflect that the evaluations of the first b-learning modality course with 44 participants present a 98% approval rate compared to the second e-learning mod...

Teacher training can assist in initiating digital changes in education. However, to achieve this, the training should use leading examples from the field of digital education solutions and technologies, while university and school educators should be trained to apply them in their work and to create high-tech educational startups in the field of e-learning. The goal of this study was to increase the professional competencies of teachers by conducting a corporate course that would prepare the teachers of the university in Yakutia to apply e-learning methods. The article demonstrates that the introduction of e-learning at the university is an important comprehensive process that implies transformation of all education components under the influence of modern technologies. Its practical implementation requires changing the goals, organizational forms, and technologies of educational activit...

The objective of the research work was to propose a teaching method that allowed the self-management of knowledge related to the zoology of invertebrates by the students of the 3rd year of the Bachelor of Education career, comparing in-person learning vs. those not in attendance. For the development of the research, information gathering and processing methods were used, which allowed us to verify the shortcomings in terms of the use and elaboration of this type of teaching medium, for the teaching-learning process from the non-face-to-face modality. The illustrations were made to correspond with the pedagogical and hygienic requirements, which contributed to the aesthetic education of the students and raised the interest in the didactic material. Suggestions and arguments made by different experts were taken into consideration, which were largely the basis for the realization of the wor...

The virtual classroom is an innovative educational resource that allows teachers and students to access and use of various media (chat, web pages, discussion forums, blogs, wikis, etc); in order to perform activities that are conducive to learning. The use of this resource will help optimize the teaching-learning process in person, because it creates a development environment and collaborative work between all actors of learning. This will maintain effective communication between students and teachers. This research was conducted during the academic semester 2016-II, applied to students of the Faculty of Architecture and Urbanism of the Private University of Tacna, regarding the use of virtual classrooms. They were part of the sample 300 students of different cycles. Objective: The objective is to identify the perception of college students from the Faculty of Architecture and Urbanism a...

In this study, we address a fundamental and still relatively less explored aspect in the field of neural networks for image dehazing: the unsupervised dehazing of an image. By conceiving a hazy image as the superposition of several “simpler“ layers, such as a haze-free image layer, a transmission map layer, and an atmospheric light layer, inspired by the atmospheric scattering model, we propose an approach based on the concept of layer disentangling. Our method, called XYZ, represents a substantial improvement in image quality metrics, such as SSIM and PSNR as well as BRISQUE, PIQE and NIQE. This advancement is achieved through the strategic combination of the XHOT, YOLY and ZID methods, capitalizing on the individual strengths of each. A distinctive and valuable aspect of the XYZ approach is its unsupervised nature, which implies that it does not rely on data sets containing pairs o...

Education is one of the largest markets promoting implementation of Bring Your Own Device BYOD. The BYOD model was originated in colleges and universities, being stimulated by technologically advanced students, who demanded it, and administrators of educational entities, who agreed that allowance to get access to the network using personal devices was a competitive advantage. Nowadays this concept attracts great attention. People depend on their personal devices and want to have the opportunity to use them anywhere in order to make their life simpler and more efficient. While BYOD implementation increases, teachers determine new methods of integration of mobile devices into learning. The use of personal mobile devices of students for learning seems to be attractive for universities, since these devices would help to reduce expenses and to support teaching and learning.

In biometrics technology, the fingerprint identification problem has been widely studied over the last decades due to its applicability in person identification cases. In casualty cases, recognition of the victim is required, which should be done unequivocally using fingerprint identification. The aim of this research is to innovate the fingerprint identification process, developing an efficient search method in a large database that allows finding a fingerprint in less time by classifying fingerprints into segments, according to their closest characteristics, using machine learning. Then, in a given segment, a discrete linear search algorithm is applied, with which the required fingerprint is located.
