Denoising diffusion probabilistic models (DDPMs) have demonstrated significant potential in addressing complex image processing challenges. This paper explores the application of DDPMs in three different areas: reconstruction of remote sensing imagery affected by cloud cover, reconstruction of facial images with occluded areas, and segmentation of bodies of water from remote sensing imagery. Inpainting involves filling in missing regions in images, while DDPMs act as data generators capable of synthesizing information that alings coherently with the context of the original data. Inspired by the inpainting technique, the RePaint approach was adapted and applied to reconstruction tasks. The WaterSegDiff approach, which uses a diffusion model as a backbone, was employed for the segmentation task. To illustrate the model’s behavior and provide examples of the tasks, experiments were carrie...

It is known that 33% of traffic accidents worldwide are caused by drunk driving or drowsiness [1] [2], so a drowsiness level detection system that integrates image processing was developed with the use of Raspberry Pi3 with the OpenCV library; and sensors such as MQ-3 that measures the percentage of alcohol and the S9 sensor that measures the heart rate. In addition, it has an alert system and as an interface for the visualization of the data measured by the sensors a touch screen. With the image processing technique, facial expressions are analyzed, while physiological behaviors such as heart rate and alcohol percentage are measured with the sensors. In image test training you get an accuracy of x in a response time of x seconds. On the other hand, the evaluation of the operation of the sensors in 90% effective. So the method developed is effective and feasible.

Within the framework of the Secondary School Accompaniment Program of the Social Space of Llefi à, Badalona (Barcelona, Spain), I carried out a photography workshop whose main objective was to allow young people to experiment with the photographic image and build personal visual narratives. This proyect proposes to understand the photographic experience as a process and not only as an aesthetic result. The article aims to account for the methodology used in the collaborative construction of a workshop and, this way, narrate the dynamics, encounters and links that can be generated from the photographic learning and the resulting images.

The learning process in training children with visual impairments and low vision requires the use of new devices that integrate image recognition and feedback on stimulation sequences with the senses of tactile and auditory responses into their design. Eighteen students with visual impairments (blind or low vision) between the ages of eight and twelve, who attend a school specialized in teaching children with visual impairments, completed three numerical stimulation routines. The software developed evaluates skills of addition and subtraction, identification of geometric shapes, and mental calculations to achieve a goal. The results of the test showed that the students performed better in the game dynamic than in the addition and subtraction routines. This study is a contribution to designing software for low-cost devices as it has been verified that this type of application works on bot...

En los últimos años, el uso de cámaras multiespectrales ha ido en aumento debido a su capacidad para analizar diferentes características de los materiales. Así, múltiples métodos para desarrollarlas están siendo estudiados. Un nuevo prototipo de una camara multiespectral de tipo multiespectral filter array, que utiliza nanowires como filtros, se ha desarrollado en el grupo de investigación de Nanophotonics de la universidad de Harvard. En este tipo de cámara, se sobrepone un filtro en cada uno de los píxeles del sensor para capturar una banda específica de la luz. Debido a que el prototipo está en fase de desarrollo, no cuenta con todas las funciones que una cámara multiespectral debería tener. Este trabajo se centró en desarrollar una de estas funciones, la cual es la reconstrucción de imágenes a color a partir de sus nueve bandas capturadas El desarrollo de la funció...

The creation of a Virtual Lab, integrated and interactive software, to perform histogram-based binarization of gray scaled images is reported. In an attempt to optimize the binarization the developed virtual lab introduces a Heuristic Binarization Threshold. At processing time, the module extracts the histogram of the input gray scaled image, and then a Heuristic Threshold is calculated by taking the weighted average of the foreground grey levels of the image. Next those pixels in input image whose grey levels are above this threshold are highlighted. Although still not experimentally optimum, this heuristic threshold provides a first approximation towards automatic optimum binarization of grey scaled images. For comparison purposes when an input image is operated on by the binarization module, it is possible to visualize up to three different binarizations on screen simultaneously, each...

In order to evaluate the forms of interaction in the main Instagramers from Peru and Colombia, an exploratory analysis of their profiles was carried out on the Instagram audiovisual platform during 2019. For this reason, firstly, the Heepsy tool was used to establish the influencers with greater impact within the platform in both countries and then, through the monitoring tools Fan Page Karma and Social Blade, to determine a set of variables and parameters regarding their interaction. The results show that the audience index is higher for Instagramers from Colombia than for the ones from Peru. In addition, there is a clear trend among digital audiences to value content through likes as a sign of interaction with it, but on the other hand, there is a representative decrease in expressing their impressions with words and comments regarding what they observe; this is also established by the...
