Abstract :
A hybrid motion/pattern adaptive scheme for the conversion of interlaced video sequences to the progressive format is presented. It normally operates in the temporal interpolation model and switches to spatial interpolation when motion is detected. The filter for spatial interpolation is adapted according to the local image pattern. Directional filters are designed for oriented features based on their representation by oriented polynomials. Although the proposed scheme has only been applied to the interpolation of interlaced signals, its principle is applicable to other problems in video signal resolution enhancement
