    The increasing number of ITS (Intelligent Transportation Systems) equipment spread across cities offers tre- mendous possibilities in the development of distributed smart environments. A middleware layer located be- tween the operating system and the fi nal application can be used for the communication among the equipment to spontaneously act and cooperate among themselves. However, this middleware layer has also a computational cost that should be quanti fi ed as it can affect the main application. This paper de fi nes a methodology for such quanti fi cation using as case example a modern ITS equipment related to vehicle tracking using arti fi cial vision. Experimental results illustrate the proposed methodology.Ministerio de Educaci贸n y Ciencia DPI2007-60128Consejer铆a de Innovaci贸n, Ciencia y Empresa P07-TIC-0262

    Las enfermedades transmitidas por mosquitos se consideran emergentes y en constante aumento debido al crecimiento de la poblaci贸n y cambio clim谩tico. Con el fin de monitorear la ocurrencia de brotes de larvas de mosquitos, una identificaci贸n de larvas. Se ha desarrollado un sistema basado en la detecci贸n y clasificaci贸n de objetos mediante visi贸n artificial y aprendizaje autom谩tico desarrollado y evaluado. Para ello, se utilizaron 45 im谩genes de muestra de un recipiente con agua que conten铆a Se han recolectado mosquitos en estado larval y pupal. El detector basado en la umbralizaci贸n adaptativa y la detecci贸n de contornos pudo encontrar todos los objetos relevantes en las im谩genes de muestra. Para identificar cada objeto encontrado por el detector como larva o no, un clasificador basado en HOG y SVM, y otro basado en CNN han sido entrenados y evaluados, obteniendo valores F1 de 0.951 y 0.991 respectivamente.CONACYT - Consejo Nacional de Ciencia y Tecnolog铆aPROCIENCI

    Get PDF
    Intelligent transportation systems (ITS) in urban environments are based today on modern embedded systems with enhanced digital connectivity and higher processing capabilities, supporting distributed applications working in a cooperative manner. This paper provides an overview about modern cooperative ITS equipments and presents a distributed application to be used in an urban data network. As a case example, an application based on an embedded CORBA-compliant middleware layer and several computer vision equipments is presented. Results prove the feasibility of distributed applications for building intelligent urban environments

    Definition and Application of a Computational Parameter for the Quantitative Production of Hydroponic Tomatoes Based on Artificial Neural Networks and Digital Image Processing.

    This work presents an alternative method, referred to as Productivity Index or PI, to quan tify the production of hydroponic tomatoes using computer vision and neural networks, in contrast to other well-known metrics, such as weight and count. This new method also allows the automation of processes, such as tracking of tomato growth and quality control. To compute the PI, a series of computational processes are conducted to calculate the total pixel area of the displayed tomatoes and obtain a quantitative indicator of hydroponic crop production. Using the PI, it was possible to identify objects belonging to hydroponic tomatoes with an error rate of 1.07%. After the neural networks were trained, the PI was applied to a full crop season of hydroponic tomatoes to show the potential of the PI to monitor the growth and maturation of tomatoes using different dosages of nutrients. With the help of the PI, it was observed that a nutrient dosage diluted with 50% water shows no difference in yield when compared with the use of the same nutrient with no dilution.CONACYT - Consejo Nacional de Ciencia y Tecnolog铆aPROCIENCI

    Se puede elegir el agua para beber o los alimentos para comer, pero no se puede elegir el aire para respirar. La contaminaci贸n del aire es un problema primordial, que influye directamente en la salud de las personas, el bienestar general de una comunidad y su desarrollo socioecon贸mico. Para poder gestionar esta problem谩tica y tomar las decisiones adecuadas en pos de una soluci贸n se necesita conocer el estado de la calidad del aire y tener un diagn贸stico del problema.CONACYT 鈥 Consejo Nacional de Ciencia y Tecnolog铆aPROCIENCI
