We call these irrelevant\u00a0frames stop-frames and propose a simple algorithm\u00a0to identify and exclude them during classifier training. Stop-frames\u00a0might appear in any video, so it is hard to recognize\u00a0their category. Therefore we identify stop-frames as those\u00a0frames, which are commonly misclassified by any concept\u00a0classifier. Our experiments demonstrates that using our algorithm\u00a0improves classification accuracy by 60% and 24%\u00a0in terms of mean average precision for an event and concept\u00a0detection benchmark.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The ICMR2014 paper by Amirhossein Habibian and Cees Snoek entitled Stop-Frame Removal Improves Web Video Classification\u00a0is now available.\u00a0Web videos available in sharing sites like YouTube, are becoming\u00a0an alternative to manually annotated training data,\u00a0which are necessary for creating video classifiers.
