Abstract
A motion adaptive deinterlacer (MADI) receives two pairs of interlaced fields from a current frame and a reference frame of an input video. The MADI deinterlacer filters noise of the received interlaced fields and detects edges of the received interlaced fields. From the detected edges, the MADI deinterlacer spatially interpolates an output pixel using directional filtering. The MADI deinterlacer also detects motion of the output pixel and calculates temporal constraints of the output pixel based on same parity field difference and/or opposite parity field difference. Based on the temporal interpolation and spatial interpolation of the output pixel, the MADI deinterlacer blends the temporal and spatial interpolation of the output pixel to generate an output pixel in progressive format.
