Abstract
In a method of de-interlacing video data (F), at least three different de-interlacing algorithms (VTF, MED1, CM3) are applied on the video data (F) to obtain at least three de-interlaced signals (DIO-1, DIO-2, DIO-3), no majority of de-interlacing algorithms copying a single spatio-temporally neighboring pixel (A, B, C, D) to the interpolated position (E), and the at least three de-interlaced signals (DIO-1, DIO-2, DIO-3) are order statistical filtered (MED2) to obtain an output signal (E).
Claims9
A method of de-interlacing video data, the method comprising the steps:
- applying at least three different de-interlacing algorithms on the video data to obtain at least three de-interlaced signals, no majority of de-interlacing algorithms copying a single spatio-temporally neighboring pixel to the interpolated position;
- and
- order statistical filtering the at least three de-interlaced signals to obtain an output signal.
A device for de-interlacing video data, the device comprising:
- means for applying at least three different de-interlacing algorithms on the video data for forming at least three de-interlaced signals, no majority of de-interlacing algorithms copying a single spatio-temporally neighboring pixel to the interpolated position;
- and
- means for order statistical filtering the at least three de-interlaced signals to obtain an output signal.
