Análisis de actividad en vídeos de baloncesto

Abstract

El gran abanico de posibilidades de trabajo que ofrecen los sistemas de análisis de contenido en vídeos deportivos hizo que se desarrollase en el grupo de procesamiento de vídeo (VPU-Lab) de la Escuela Politécnica Superior de la Universidad Autónoma de Madrid una aplicación interactiva de detección y seguimiento de jugadores. Este prototipo consistía en la mejora de usabilidad e interacción con el usuario final de un sistema ya realizado previamente en el cual se conseguían buenos resultados tanto de detección como de seguimiento. Dicha aplicación se había creado tanto para deportes individuales como colectivos, pero en este último caso sólo trabajaba con vídeos de fútbol. Debido a esto, surgió una nueva línea de investigación que consistía en la adaptación de este prototipo a otro deporte colectivo como es el baloncesto. Por tanto, en este proyecto se ha trabajado sobre esa línea, solucionando la problemática presente y creando un primer prototipo sobre el cual seguir investigando y desarrollando. Se trabajó en la adaptación de la programación del sistema para que se pudiese ejecutar con un número distinto de vídeos entrantes. A continuación se modificó la interfaz gráfica para que pudiese representar de una forma óptima los nuevos resultados obtenidos, manteniendo toda la funcionalidad que tenía en el anterior prototipo. Seguidamente, se investigó la mejora de los resultados obtenidos en estos nuevos vídeos con el sistema que estaba implantando. Se trató de obtener los mejores resultados posibles tanto de detección como de seguimiento ajustando diferentes parámetros. Por último, puesto que la interfaz es la plataforma visible de este proyecto, se ha trabajado en mejorarla dotándola de un nuevo módulo de creación de la homografía que hace que se simplifique aún más el uso de esta interfaz por el usuario.

The large range of functional possibilities that content analysis systems o er in sports videos has prompted the development, in Escuela Politécnica Superior of the Universidad Autonoma de Madrid, of an interactive detection and tracking application for players. This prototype consisted of a usability and end-user interaction improvement of a previously known system in which both detection and tracking results were satisfactory. Such application had been created both for individual and collective sports, but in this last case, it only worked for soccer videos. Due to this, a new line of investigation arose, that consisted in the adaptation of this prototype to another sport such as basketball. Therefore, this Project has worked among the same lines, solving the existing issues and creating a similar prototype on which to continue investigation and further development. The system programming was adapted, in order to be able to be executed with a di erent number of inputted videos. Following this, the graphic interface has been modi ed, to be able to optimally represent the newly obtained results, maintaining the full functionality of the previous prototype. Furthermore, an improvement of the obtained results in these new videos was researched, with the system that was being implanted. The goal was to obtain the best possible results in both detection and tracking by adjusting di erent parameters. Lastly, due to the interface being the visible part of this project, there have been updates made to improve it, by including a new homography creation module, that simpli es the use by the end user even more.
