Aportacions als sistemes de reconeixement de logotips en esdeveniments esportius

Abstract

[CATALÀ] Aquesta memòria presenta un sistema per detectar logotips en esdeveniments esportius. El sistema es basa en els mètodes de reconeixement d’objectes utilitzats actualment que consisteixen en la extracció de patrons que representen al objecte i la cerca d'aquests a l'escena. La implementació d’un d’aquests sistemes proposat per David Lowe ofereix una bona precisió i una taxa de reconeixement acceptable. Adicionalment en aquest treball també es proposa una millora del temps d’execució que consisteix en la agrupació de patrons utilitzant grafs. Aquesta millora és aplicable no només al reconeixement de logotips sinó al de qualsevol tipus d’objecte.

Adicionalmente, en este trabajo se propone una mejora del tiempo de ejecución que consiste en la agrupación de los patrones utilizando grafos. Esta mejora es aplicable no sólo al reconocimiento de logotipos sino al de cualquier tipo de objeto.

[ANGLÈS] This report presents a system to detect logotypes in sport events. It is based on the actual methods used to recognize objects, which look for patterns extracted from them. The implementation of David Lowe’s version shows a good precision and recall for this task. Additionally, a new clustering technique that speeds up the execution time thanks to the use of graphs is proposed. This improvement can be applied not only to logos but to any kind of object.
