Abstract

Methods for motion compensated frame rate upconversion exploit motion in order to generate interpolated frames that are temporally located between the available original frames of a video sequence. When the interpolated frames are inserted into the original sequence, the resulting sequence has a higher visual quality due to the increased frame rate. We propose a method for motion compensated frame rate upconversion which reduces upconversion artifacts by combining multiple intermediate interpolations utilizing median filtering. We use an efficient block based motion estimation method which makes use of motion vectors extracted from an H.264 bitstream. Low computational complexity makes the method suitable for real time operation.
