Super-resolution based coding approach for H.264 standard
In literature video coding efficiency of H. 264 standard has been improved using decoder-side super-resolution (SR). In this paper SR estimation is used during encoding in place of skip/direct mode prediction of H. 264 ...
Decoder side candidate motion vector selection for B-frames in H.264 video coding
In H.264 standard, because of differential coding of motion vectors, sudden motion changes in object boundaries increase the amount of bits used for coding especially at low bitrate regimes. In this paper, we propose a ...
A survey of algorithms and architectures for h.264 sub-pixel motion
(WORLD SCIENTIFIC PUBL CO PTE LTD, 2012-05)
This paper reviews recent state-of-the-art H. 264 sub-pixel motion estimation (SME) algorithms and architectures. First, H.264 SME is analyzed and the impact of its functionalities on coding performance is investigated. ...
Fast algorithm analysis and bit-serial architecture design for sub-pixel motion estimation in H.264
(World Scientific Publishing Company, 2010-12)
The sub-pixel motion estimation (SME), together with the interpolation of reference frames, is a computationally extensive part of the H.264 encoder that increases the memory requirement 16-times for each reference frame. ...
Decoder-side super-resolution and frame interpolation for improved H.264 video coding
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 ...
Decoder side true motion estimation for very low bitrate b-frame coding
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 ...
