UNIT FOR AND METHOD OF DETECTION A CONTENT PROPERTY IN A SEQUENCE OF VIDEO IMAGES

摘要

A method of detection of a content property in a data stream on basis of low-level features is proposed. The method comprises: determining (202) a behavior feature (e.g. 320) from a sequence of the low-level features; determining (204) to which one of the predetermined clusters (304) of behavior features (318-328) within a behavior feature space (300) the determined behavior feature (320) belongs; determining a confidence level of the content property presence on basis of the determined cluster (304) of behavior features and the determined behavior feature; and detecting the content property on basis of the confidence level of the content property presence.
