MOTION COMPENSATING FIELD INTERPOLATION METHOD USING A HIERARCHICALLY STRUCTURED DISPLACEMENT ESTIMATOR |
摘要 |
A motion compensating field interpolation method which allows the interpolation of several fields between every two transmitted fields of a digital television sequence. Using the model of translatorily displaced objects, a hierarchically structured displacement estimator is applied to cope with relatively large displacements. It provides a displacement vector with integer components for each picture element of the fields to be interpolated. A change detector is used to assure zero displacement vectors in unchanged areas. A two-coefficient spatio-temporal filter interpolates each picture element of the fields to be interpolated. |
