Verfahren und Vorrichtung zur Ermittlung der Zuverlässigkeit eines Bewegungsvektorfeldes |
摘要 |
The method includes a stage of calculating a stability parameter Det_Stab(t) for the field, on the basis of a comparison (4), over two successive images, of the number of occurrences of the majority vectors of the movement-vectors fields of each of these images, a field being defined as stable if the variation in the number of occurrences lies within a predefined bracket, and a stage of deciding on reliability (7) on the basis of this stability parameter. Applications relate to frequency converters and video coders. <IMAGE> |
