Quad-Tree Motion Estimation in the Frequency Domain
We propose a quad-tree scheme for obtaining sub-pixel estimates of interframe motion in the frequency domain. Our scheme is based on phase correlation and uses motion compensated ...

Motion compensated refinement for low complexity pixel based distributed video coding
Distributed video coding (DVC) is a new coding paradigm that enables to exploit video statistics, partially or totally at the decoder. A particular case of DVC, Wyner-Ziv coding, ...

Joint Rate-Distortion-Complexity Optimization for H.264 Motion Search
A joint rate-distortion-complexity H.264 motion search framework is proposed to balance the encoder’s coding efficiency and complexity in an embedded system environment. Under ...
