Recognizing film and video objects occuring in parallel in single television signal fields

摘要

Method and arrangement to detect a picture repetition mode of film material with a series of consecutive fields, the arrangement having processing means and a memory (M), the processing means being arranged to carry out the following steps: ;Identifying a plurality of different objects within the consecutive fields using a segmentation method, an object being defined as an image portion of the consecutive fields that can be described with a single motion model; ;Carrying out the following steps for each one of the plurality of objects, i.e.: ;Establishing a motion parameter pattern for each one of the objects within the consecutive fields; ;Comparing the motion parameter pattern with a number of predetermined motion parameter patterns; ;Determining the picture repetition mode for each one of the objects using the result of the preceding step.
