Abstract:
1. A method of discriminating an obscene video using a time-based feature value, the method comprising: (a) forming a first time-based flow of predetermined feature values varying with the lapse of time according to a first time interval of one or more types of videos and the videos being normalized in their entirety according to a predetermined duration, wherein the first time-base flow represents a first pattern of obsceneness for a duration of the corresponding video; (b) extracting the predetermined feature values varying with lapse of time according to a second time interval from an input video for which obsceneness is to be determined and the input video being normalized in their entirety according to the predetermined duration, and forming a second time-based flow of the extracted predetermined feature values, wherein the second time-base flow represents a second pattern of obsceneness for a duration of the corresponding video; and (c) determining the obsceneness of the input video by comparing the first and second time-based flows and calculating a loss value between the first time-based flow and the second time-based flow.
