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

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 behav...

Zusammenfassung:	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.
