Abstract

Embodiments of the present invention provide an edge adaptive spatial temporal deinterlacing filter that evaluates multiple edge angles and groups them into left-edge and right-edge groups for reconstructing desired pixel values. A leading edge is selected from each group, forming the final three edges (left, right and vertical) to be determined. Spatial temporal filtering is applied along the edge directions.
