A system for automatic detection and recognition of advertising trademarks in sports videos
Lamberto Ballan, Marco Bertini, Arjun Jain · 2008
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 firm1 with the aim of evaluating the visibility of advertising trademarks in broadcast sporting events. We propose a semi-automatic system for detecting and retrieving trademark 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.
