spatial redundancy

spatial redundancy

Elements that are duplicated within a structure, such as pixels in a still image and bit patterns in a file. Exploiting spatial redundancy is how compression is performed. Contrast with temporal redundancy. See intraframe coding and data compression.

The Bladeserversysteme to be procured should be installed in existing Bladecenter of type HPE Bladecenter C7000 to ensure a spatial redundancy.
Thus, IntraBC exploits spatial redundancy within a specified search range.
To achieve high compression efficiency while maintaining acceptable complexity, we propose a texture compression method to reduce the spatial redundancy between blocks by using the block-matching method.
There may be some possibility of placement of extra sensors which will result in spatial redundancy, temporal redundancy or information redundancy (Daniel-Ioan et al.
There are different categories of Redundancy such as Spatial Redundancy, Temporal Redundancy and Information Redundancy.
Each GOP is a sequence of frames encoded as: intra frame (I frame), if only spatial redundancy is exploited for the frame compression; prediction (P frame) from previous frames, if both temporal and spatial redundancy are exploited for the frame compression; bidirectional (B frame) prediction when the temporal prediction is computed from previous and future frames.
I frames are encoded exploiting spatial redundancy for the compression.
Atheros SST increases the total transmit power and spatial redundancy, ensuring dropout-free coverage.
The remaining signal (prediction error) is further compressed with spatial redundancy reduction (DCT).
