Electro encefalograma (EEG), emociones, procesamiento de señales, Transformada Discreta Wavelet (DWT), interfaces cerebro-computador (BCI), redes neuronalesResumo
En el trabajo se aborda una revisión bibliográfica en el campo de la detección de emociones. Se muestra el gran impacto de las aplicaciones de interfaz cerebro-computador (BCI) y su funcionalidad. Se explica cómo trabajar con las señales neuronales y cómo extraer información de ellas utilizando la Transformada Discreta Wavelet (DWT). También se mencionan los métodos que se usan para la clasificación y caracterización. El objetivo del escrito es revisar el estado del arte para establecer las bases de un proyecto que busca analizar los parámetros del cerebro cuando un televidente observa un comercial publicitario.
