Reconocimiento de patrones numéricos para vuelo controlado de un AR Drone utilizando redes neuronales artificiales

In this paper the letter segmentation of photographs was used, taken from a Parrot AR Drone’s camera with the aim of establishing a stimulusresponse, where the original picture formed by Red, Green and Blue (RGB) colors was segmented by color (choosing the red channel). Once the character is recognized, the Drone executes the corresponding action. Noise-free number patterns were initially used and then some pixels were added in the image in order to make a set of patterns more robust, which provided the training set for neural network and thus are able to interpolate new patterns. Edge techniques detection were used for image segmentation including Sobel filter and filters for noise removal based on the median filtering, that is a low pass filter. All this took place in a closed environment, expecting to extend this to different environments. 61 Research in Computing Science 107 (2015) pp. 61–71; rec. 2015-08-04; acc. 2015-10-19
