There are provided methods and apparatus for reduced resolution partitioning. An
apparatus includes an encoder for encoding video data using adaptive tree-based frame …

We present a theory for the optimal bit allocation among quadtree (QT) segmentation,
displacement vector field (DVF), and displaced frame difference (DFD). The theory is …

This paper describes a method for motion-compensated compression of video sequences.
The proposed method enables very efficient encoding of video frames partitioned into …

While motion fields estimated by maximizing the temporal prediction quality tend to be noisy
and demand a large number of bits to encode, finding the motion vectors (MVs) that allow …

This paper reports two efficient quadtree-based algorithms for variable-size block matching
(VSBM) motion estimation. The schemes allow the dimensions of blocks to adapt to local …

Motion estimation and compensation is widely used for exploiting temporal correlation within
an image sequence. To find motion vectors that lead to high compression, most motion …

This paper describes research related to the development of fast compression end playback
routines for full screen, full motion color video and audio suitable for use on the IFTE Soldier …

We propose an optimal quadtree (QT)-based motion estimator for video compression. It is
optimal in the sense that for a given bit budget for encoding the displacement vector field …
