    En el presente trabajo se ha planteado un novedoso algoritmo, basado en la tecnolog铆a de Adress-Event, que extrae el flujo 贸ptico desde eventos. Para realizar dicho proceso, se ha realizado un estudio de los distintos algoritmos cl谩sicos de flujo 贸pticos, como el Lucas-Kanade, block-matching, Horn-Shuncky Elementary Motion Detector. Este 煤ltimo es el algoritmo que se ha estudiado con m谩s profundidad al ser un candidato id贸neo para ser implementado en hardware. Se ha desarrollado una versi贸n mejorada de este filtro, extendiendolo a todas las posibles combinaciones de eventos. Para finalizar, este trabajo se ha culminado con la implementaci贸n de una versi贸n en software de dicho filtro usando el framework de Java, jAER. Una vez que se ha llevado a cabo la implementaci贸n, se ha realizado una comparaci贸n con los diversos tipos de filtros que ya han sido implementados en jAER para extraer m茅tricas de velocidad de procesamiento y m茅tricas de linealidad y, de esta manera, poder comparar entre los distintos algoritmos de flujo 贸pticos considerados.In this work, it has been studied the optic flow in adress-event framework. As principal algorithm, the "Elementary Motion Detector" has been studied. This algorithm has been extended to accept all possible combination of events. The final algorithm has been implemented in Java through jAER framework, and it has been obtained the results for distinct type of optic flow filters.Universidad de Sevilla.

    Performance Evaluation of Neural Networks for Animal Behaviors Classification: Horse Gaits Case Study

    The study and monitoring of wildlife has always been a subject of great interest. Studying the behavior of wildlife animals is a very complex task due to the difficulties to track them and classify their behaviors through the collected sensory information. Novel technology allows designing low cost systems that facilitate these tasks. There are currently some commercial solutions to this problem; however, it is not possible to obtain a highly accurate classification due to the lack of gathered information. In this work, we propose an animal behavior recognition, classification and monitoring system based on a smart collar device provided with inertial sensors and a feed-forward neural network or Multi-Layer Perceptron (MLP) to classify the possible animal behavior based on the collected sensory information. Experimental results over horse gaits case study show that the recognition system achieves an accuracy of up to 95.6%.Junta de Andaluc铆a P12-TIC-130
