Coding with variable block maps
In this article we study a special class of sliding block maps that we call variable block maps.We characterize the subsets of finite and infinite sequences that can be obtained as the image of another subset of symbolic sequences by a variable block map. On the other way, we show that the coding process induced by such kind of block maps can be reversed, even with partial knowledge about the v...
متن کاملVariable Size Block Matching Motion Coding
Recently developed object-based video coding schemes require the estimation of motion in arbitrary-shaped objects. A quad-tree structured variable size block matching technique is described. The inherent motion is represented by significantly fewer blocks than if conventional fixed size block matching had been used to provide a similar quality prediction.
متن کاملVideo Coding with R - D ConstrainedHierarchical Variable Block Size ( VBS )
The variable block size(VBS) motion estimation technique allows for larger blocks to be used when smaller blocks yield little gain, saving bit rates especially for areas containing more complex motion. However, the employment of the VBS motion estimation technique introduces a new optimization issue for the motion compensated transform coding, because an increase in bit rate allocation is neces...
متن کاملVariable Block-size Image Coding by Resource Planning
An image coding, and compression, technique is presented, where an image is segmented and encoded into blocks of variable block-sizes (VBS). Conventional quad-tree algorithm imposes excessively rigid rules on the placement of blocks, causing ineffective segmentation of the image. Although several algorithms have been proposed to alleviate these constraints, they all impose fixed scanning order ...
