In this paper, a decoder side motion vector derivation scheme for inter frame video coding is proposed. Using a template matching algorithm, motion information is derived at the decoder instead of explicitly coding the information into the bitstream. Based on Lagrangian rate-distortion optimisation, the encoder locally signals whether motion derivation or(More)
The ongoing increase of computing performance facilitates a higher algorithmical complexity in video coding systems. The decoder may be able to estimate or derive prediction parameters based on the previously decoded signal. In this paper we present an extension to H.264/AVC where the explicit coding of motion parameters is adaptively replaced by a template(More)
Decoder-side motion vector derivation (DMVD) using template matching has been shown to improve coding efficiency of H.264/AVC based video coding. Instead of explicitly coding motion vectors into the bitstream, the decoder performs motion estimation in order to derive the motion vector used for motion compensated prediction. In previous works, DMVD was(More)
