Claim One:
1. An apparatus for generating discriminant functions for distinguishing obscene videos using visual features of video data, comprising: a frame set generator which categorizes videos and then generates a first frame set including a predetermined number of frames and a second frame set including frames selected from the first frame set; a discriminant value generator which extracts visual features of frames of the second frame set and then generates a first discriminant value by generating a frame based discriminant function and determining whether each frame of the first frame set contains obscene video data; a group frame based discriminant value generator which creates a group of frames included in the first frame set, then generates a group frame based discriminant function by extracting visual features of the group, and then determines whether each frame of the group contains obscene video data; and a third discriminant function generator to which the first and second discriminant values are input and which generates a synthetic discriminant function by using a statistical discriminant analysis method, a machine learning method, or a rule generating method.
