A new method for the characterization of telecine effect in video sequences ?
A great deal of the audiovisual content used for broadcasting and automatic video indexing comes from film. This film content has to undergo a conversion of its frame rate, from 24 fps , the characteristic frame rate of film recording, to 25 fps or 30 fps which are the frame rates used in TV broadcasting. This conversion is carried out by a telecine and consists of a periodic repetition of fields. In many applications the need arises to reverse this conversion (inverse telecine). This paper presents a statistical method for automatic removal of the repeated fields present in the video sequence. The method consists of two steps: the first is to determine, using an energy detector, if the sequence has been telecined. Then, the two parameters necessary for removing the telecine effect are determined: the system for which the film has been telecined (for NTSC or PAL system) and the location of one repeated field.
