Emergency situations are occurring more frequently as a result of global warming. Most of the information that have is based on remote sensing, product of the different space missions, known as satellites, which provide satellite images, information of the meteorological behavior, among others. To be able to work with these tools, it is necessary to have a workstation with good computational chara...Show More
Technological surveillance has become one of the ways of knowing how technology is developing in a particular area. In a normal situation, Internet search engines are used to browse the pages of equipment manufacturers to analyze. With the use of Artificial Intelligence, mainly those that allow information to be provided about the questions asked, as is the case of CHATGPT. In the work presented, ...Show More
Post-traumatic recovery is a long and painful process, mainly those related to the lower limbs, where recovery is prolonged mainly by the concern of achieving a balanced recovery in posture. In the present work we present a low cost method for the evaluation of recovery in posture, based on the evaluation of the symmetry of the lower limbs, in order to evaluate the recovery of posture, the method ...Show More
In these times, where technology is being used in many processes and where Artificial Intelligence is presenting new tools for many technological problems, in this work, A low-cost mechanism for setting up a super-portable computer is presented, for field work, where advanced processing is required, with the use of a GPU, for this work, I worked with the Tegra TKI card, from the Nvidia family, whi...Show More
The information and communication technologies are helping to solve problems related to the health sector, one of them is related to control the mosquito outbreak that transmits the disease “Denge”, the methodology that is presented, is formed by the installation of a trap for the mosquito to lay their eggs, this trap is monitored by a camera that records continuously 24 hours a day and night, the...Show More
Information and communication technologies allow us to develop solutions and applications in different areas of knowledge; one of them is related to the monitoring of the planet, in this line, in the use of satellite images to monitor land cover use. The lagoons are a source of water for most of the people who live in high Andean areas, these areas are surrounded by mountain ranges that make acces...Show More
The Covid-19 pandemic, achieved a growth in digitization processes, in the health sector, many solutions were presented to mitigate the impact of the pandemic, in this sense, we present the implementation of a low cost system, to know the location of positive patients or patients who are waiting for test results, as well as to warn them, One of the functionalities of the system is the bidirectiona...Show More
In the studies of medical images, being able to classify the objects present in the images is of vital importance; these objects can be some structure of the human body, some malformation, and tumors, among others. One of the fundamental tasks is to be able to find the characteristics that help to classify the desired object; these characteristics can be found manually using mainly shape and color...Show More
Epilepsy is one of the characteristic diseases of brain activity. People with this disease live with the symptoms and try to control the events to mitigate the effects that they may cause, such as a fall, blow, or any other consequence. In these times of pandemic caused by COVID-19, many of the people who have this disease present many events in a row, which can be caused by many factors, such as ...Show More
Currently, digital technologies are widely used to record any event by using different types of cameras, for different uses. There are cameras that use an optical sensor, which generates images in the RGB model. There are some cameras that use thermal sensors, which perform the registration of the temperature of the object being recorded and presents them under a color model using a color map. Thi...Show More
Currently, recognition systems based on the use of Artificial Intelligence techniques, are being used more frequently. For these systems to be trained, it is necessary to have a series of training images, known as dataset of images. This research study demonstrates a novel method to create a dataset of different types of images, with a demonstration applied to fundus images, in order to recognize ...Show More
Thermal images are being used more frequently in the monitoring and evaluation of thermal behavior in many areas. This study focuses on presenting a method to evaluate the thermal behavior in natural crops that are located more than 3000 meters above sea level. These natural plants are a natural representation of the vegetation that covers the Andes of South America. As they are not cultivated, no...Show More
Currently, video cameras are used in many applications, from security to recognition mechanism, all based on the analysis of images and videos, these records are made in most cases for continuous periods of recording, which is why they have large video storage weight on hard drives, in this paper, we describe a method to analyze images of high weight, using the graphic processing units known as GP...Show More
With the growth and development of autonomous electronic devices, the use and applications of batteries, which are used as a mechanism to ensure the use of these devices, is growing. At present, devices that use batteries often present some kind of damage, mainly due to misuse or ignorance in the handling of batteries, so it is important to know how batteries work and how to evaluate their conditi...Show More
The recent technological development results in developing new devices for different uses, such as applications of various uses, which can be used for many applications. This study demonstrated a novel methodology to conFigure a digital audiometer using generic devices such as the use of high-end headphones in video games, and mobile applications known as function generators, with which an audiome...Show More
Several studies have been performed worldwide to improve health services using data generated by digital medical systems. The increasing volume of data generated by these systems is making the use of knowledge discovery and data analysis techniques essential to improve the quality of the health services, which are offered by the medical facilities. However, it is possible to observe a gap, in the ...Show More
We introduce an interactive method for retina layer segmentation in gray-level and RGB images based on super-pixels, multi-level optimization of modularity, and boundary erosion. Our method produces highly accurate segmentation results and can segment very large images. We have evaluated our method with two datasets of 2D confocal microscopy (CM) images of a mammalian retina. We have obtained aver...Show More
Due to the subjective nature of the segmentation process, quantitative evaluation of image segmentation methods is still a difficult task. Humans perceive image objects in different ways. Consequently, human segmentations may come in different levels of refinement, ie, under- and over-segmentations. Popular segmentation error measures in the literature (Arbelaez and OCE) are supervised methods (al...Show More
