The purpose of this project is to classify the 27 gestures of the Colombian sign language alphabet based on the analysis of electromyographic signals using artificial neural networks. It is based on the know-how that the research group UNITEL of the Faculty of Telecommunications Engineering has regarding the processing and classification of EMG signals. The Wavelet Packet Transform-WPT transform was used to build a matrix of characteristics that allowed creating six training scenarios for the neural network for the classification of gestures of the Colombian sign language. The results obtained strengthen research in this line of work within the UNITEL research group. The accuracy value obtained in each of the scenarios using crossvalidation and confusion matrices allows the reproducibility of the classifier to be measured indirectly, since in each of them the EMG record data involves inter-subject records of the 13 subjects. In conclusion, the analysis of upper limb electromyography signals captured by the yo Armband handle through Neural Networks allows classifying the gestures of the Colombian sign language alphabet, taking into account inter and intra subjects scenarios.Ítem Diseño de una red de sensores inalámbrica para la monitorización y transmisión de datos del suelo y ambientales en tiempo real en los cultivos de palma africana(2017) Piamonte Pardo, Luis Miguel; Huerta, Mónica KarelIn this work, we examine wireless sensor networks (WSN) used as a phytosanitary medium within crops for the prevention of Bud Rot.
