On-line video filtering

Abstract

Some embodiments relate to a system and method to increase the speed of a computer determination whether a video contains a particular content. In some embodiments, the quantity of data in the video is first reduced while preserving the searched-for content. Optionally, first, the size of the data is reduced by reducing the resolution, for example resolution may be reduced without searching and/or processing the full data set. Additionally or alternatively, low quality and/or empty data is removed from the dataset. Additionally or alternatively, redundant data may be searched out and/or removed. Optionally, after data reduction, the reduced dataset is analyzed to determine if it contains the searched-for content. Optionally, an estimate is made of the probability of the full dataset containing the searched-for content.
