Resumen. El creciente desarrollo de software en el campo de visión por computadora ha sido posible gracias al uso de nuevas herramientas que facilitan la manipulación y procesado de imágenes digitales. Un ejemplo de estas herramientas son librerías como OpenCV y los lenguajes como Processing. En este trabajo se describe el uso de estas herramientas de software libre junto con el dispositivo Microsoft Kinect para detectar el gesto de apertura y cierre de manos. Para lograr la identificación de estos gestos se diseñó, implementó y probó un algoritmo que consta de cinco etapas: adquisición de la imagen, segmentación, detección de contorno, búsqueda de puntos estratégicos y reconocimiento. Se comprueba el correcto funcionamiento del algoritmo en un entorno virtual donde se traslada un rectángulo de un lugar a otro de la pantalla, mediante el gesto de sujetar y soltar de la imagen virtual.Abstract. The growing development of software in the field of computer vision has been possible thanks to the use of new tools that ease the manipulation and processing of images. -an example of these tools are the libraries like OpenCV and languages like Pocessing. In this work describes the use of these free software tools along with the Microsoft Kinect device for the detection of the gesture of opening and closing of hands. To achieve the identification of these gestures an algorithm was designed, implemented and tested, this algorithm is constituted of 5 phases: image acquisition, segmentation, contour detection, search of strategic point and recognition. The correct functioning of the algorithm is verified in a virtual environment where a rectangle is moved from one place to another on the screen, by means of the gesture of holding and releasing the virtual image.
