Technology makes many of the tasks that were previously difficult to perform, nowadays can be solved, one of them is to be able to carry out studies on large tracts of land and at the same time be able to have a level of detail of them, through the study of the satellite images provided by the Earth observation satellites, these images are composed of a series of spectral bands that will depend on the type of satellite mission that was conceived and the optical instrument that is found as a payload, these images are represented by multidimensional arrays and large size, so computational high computation equipment is required to process the images, added to this requires specialized software that allows the visual interpretation of satellite images. To be able to work with satellite images you have many configurations, normally you work with the configuration of separate bands that consis...

Accurate determination of plant water status is mandatory to optimize irrigation scheduling and thus maximize yield. Infrared thermography (IRT) can be used as a proxy for detecting stomatal closure as a measure of plant water stress. In this study, an open-source software (Thermal Image Processor (TIPCIP)) that includes image processing techniques such as thermal-visible image segmentation and morphological operations was developed to estimate the crop water stress index (CWSI) in potato crops. Results were compared to the CWSI derived from thermocouples where a high correlation was found ( = 0.84). To evaluate the effectiveness of the software, two experiments were implemented. TIPCIP-based canopy temperature was used to estimate CWSI throughout the growing season, in a humid environment. Two treatments with different irrigation timings were established based on CWSI thresholds: 0.4 (T...

FPGA-based hardware architectures are being used more frequently in many applications, thanks to the different programming languages that allow us to access them. The applications are also being varied, one of the most common areas of work with aerial images, normally acquired with cameras that are on board drones, the working mode of these configurations, is focused on being able to use visualize the images online As the flight is carried out, if you want to carry out some type of processing, it is necessary to download the image from the camera's memory, this process is already carried out when the drone has finished the flight. In this work we present a methodology to be able to use the low-cost hardware myRIO, since it has a processor and an FPGA included, we present the steps to be able to work with the device, as well as an example of online processing so that the video and images ...

Quinoa is a very important grain for human nutrition; In recent years, several research studies have addressed its nutritional use; However, one of its main weaknesses is its saponin content, which is an anti-nutrient and has a bitter taste. The debittering process involves the principle of recirculation of large quantities of water, with the purpose of reducing the consumption of this substance, it is important to develop methodologies and equipment that improve the efficiency of these traditional washing methods and reduce the work of operators and processors with the intention of making it less costly. The objective of the present research work was to design and build a quinoa de- saponifier , Amarillo Maranganí variety, to evaluate the effect of washing time (5, 10 and 15 min) and the flow of water recirculated by pumping (15, 30 and 45 L/min), on the elimination of saponin to accep...

Autonomous systems are one interesting topic recently investigated; for land and aerial vehicles; however, the main limitation of aerial vehicles is the weight to carry on-board, since the power consumed depends on this and hardware like sensors and processor is limited. The present thesis develops an application of digital image processing to detect obstacles using only a monocamera, there are some approaches but the present report wants to focus on the distance estimation approach that, in future works, can be combined with other methods since this approach is more general. The distance estimation approach uses feature detection algorithms in two consecutive images, matching them and thus estimate the obstacle position. The estimation is computed through a mathematical model of the camera and projections between those two images. There are many parameters to improve final results and t...

El presente trabajo aborda el desarrollo de una metodología para el control de los movimientos de un robot industrial del tipo cartesiano. Para ello cumple con la programación de una tarjeta de desarrollo basado en FPGA con procesadores embebidos De0_Nano_SoC y una PC, con la finalidad de posteriormente integrarlos a una máquina CNC Joyo – 2020. Los pasos seguidos son, primero, el análisis estructural utilizando el software Solidworks de la máquina CNC. Segundo, un modelamiento cinemático basado en la estructura analizada en el paso previo, con el respectivo modelado de planificación de trayectorias usando un interpolador cúbico, un algoritmo de generación de velocidades angulares propuesto por David Austin y un algoritmo de procesamiento digital de imágenes propuesto por el autor, orientado al establecimiento de trayectorias a partir de imágenes .jpg o .png. Tercero, la sim...

El presente trabajo de investigación evalúa la técnica de regresión de mapas de calor (heatmap regression - HR) para la detección automática de puntos de referencia (landmark detection) en imágenes médicas, específicamente en las imágenes de huellas plantares en dos dimensiones. El estudio se basa en la regresión de mapas de calor con aprendizaje profundo, una técnica que ha demostrado ser efectiva en la detección de puntos en rostros y en la estimación de la pose humana. Se propone un método automático para la detección de 8 puntos en las imágenes digitalizadas de huellas plantares que servirán de referencia para el diseño base de una plantilla ortopédica bidimensional, buscando así mejorar el proceso de fabricación de plantillas ortopédicas, que actualmente se realiza de forma manual y artesanal en la mayoría de los países de América Latina. La detección aut...
