spatial compression

spatial compression

Reducing digital video file sizes by compressing the pixels within each frame independently. Also known as the "intraframe" method. Contrast with temporal compression. See spatial redundancy and intraframe coding.

The SCF (spatial compression and forward) technique is proposed in [90] to manage and control traffic from the RRHs for uplink transmissions.
proposed a hybrid spatial compression algorithm and error bounded temporal compression algorithm to compress the spatial and temporal information of trajectories, respectively [18].
Semantic trajectory compression stores trajectories in the form of semantic information in road network instead of trajectory points, compresses spatial information in trajectory data by spatial compression methods, and compresses temporal information in trajectory data by temporal compression techniques, until some halting condition is met.
The process is characterized through unitary efforts of intense spatial compression [sigma] > [[sigma].sub.c] needed for material flow through space between punch and active plate.
Situated in the Tarn et Garonne region of south-west France, on the ridge of a steeply sloping valley, this house uses formal distortion and spatial compression to bring internal and external forces into tense equilibrium, Locking into views to and from key vantage points, and controlling routes and aspects across plan and section, the architects have produced a building where slants and chamfers, and nips and tucks, combine to achieve a figure of balanced eccentricity.
Because our source is an m = 2 guide, we have the opportunity to use an m = 3 or m = 3.5 guide with a vertical taper to provide spatial compression. The response to this taper is shown in Fig.
Spatial compression tries to remove 'redundant' data from within the frame, data that matters least to the eye's perception.
Hanging nearby was Arizona Landscape, 1945, a photograph in which the sun-flattened surface of the desert is punctuated by insistently vertical cactus spires, achieving a similar spatial compression in a different medium.
Spatial compression transforms small blocks of screen pixels from time-based to frequency-based signals and then filters out the high-frequency content (the eye is less sensitive to high-frequency components).
The dedicated data compression techniques for sensor nodes can be classified into two categories: (1) spatial compression techniques, and (2) temporal compression techniques.
This involves personal memory and cultural grounding, as well as perception and sensory experience; sense in this instance notably including the expanded notion of hapticity, regarding touch, muscular tension, spatial compression and expansion, and awareness of temperature and humidity.
