Decoder side true motion estimation for very low bitrate b-frame coding
(IEEE, 2011)In H.264 standard, coding of motion vectors constitutes a significant portion of total bitrate especially at low bitrate regimes. This is because differential coding of motion vectors is inefficient when the bit budget is ... -
Decoder-side super-resolution and frame interpolation for improved H.264 video coding
(IEEE, 2013)In literature decoder-side motion estimation is shown to improve video coding efficiency of both H.264 and HEVC standards. In this paper we introduce enhanced skip and direct modes for H.264 coding using decoder-side ... -
