A system for automatic detection and recognition of advertising trademarks in sports videos

In this technical demonstration we show the current version of our trademark detection and recognition system that has been developed in collaboration with a sport marketing firm 1 with the aim of evaluating the visibility of advertising trademarks in broadcast sporting events. We propose a semi-automatic system for detecting and retrieving trade-mark appearances in sports videos. A human annotator supervises the results of the automatic annotation through an interface that shows the time and the position of the detected trademarks; due to this fact the aim of the system is to provide a good recall figure, so that the supervisor can safely skip the parts of the video that have been marked as not containing a trademark, thus speeding up his work.
