Perceptual processing is a form of video optimization that accounts for two types of typically disparate compression: spatial and temporal compression. Temporal compression is compression over time, and is widely used by a number of interframe compression standards, such as H.264 and H.625, to gain significant compression advantages by looking ahead from a keyframe (or I-frame) across a long group of pictures (GoP) and compressing only what changes on a temporal basis (known as P and B frames).
proposed a hybrid spatial compression algorithm and error bounded temporal compression algorithm to compress the spatial and temporal information of trajectories, respectively [18].
The dedicated data compression techniques for sensor nodes can be classified into two categories: (1) spatial compression techniques, and (2) temporal compression techniques.
Temporal compression techniques applied in a single node can also be classified into two categories: lossless and lossy compression algorithms, which are typically based on different principles.
Edited with soft and lap dissolves, symmetrically structured by Domenico's initial approach and final departure, From the Branches appears expansive despite its temporal compression. Meyer's bracing sensibility renders every commonplace unconventional: A Belgian blonde's flirtation with Geppino, the eldest Sanna son, at a village dance curtly avoids cliche, and a little boy's theft of two fish from a monger's cart is transformed into anticlerical comedy when a gaunt, black-robed priest adjures the child to join him on a pilgrimage up a tufted hill to visit a cross and ends up with a herring in his hat.
One of the first lossy methods for data compression in WSN, lightweight temporal compression (LTC) [5], approximates the data collected by each sensor node in a WSN by a set of lines.

The temporal compression matrix [[PHI].sub.q] of size Q x E (Q < E) is defined and indicated as a sampling process in A2I converter with Q/E ratio of Nyquist sampling rate.
The spatial and temporal compression ratio is set as [kappa] = 0.75 and [eta] = 0.72 (K' = 3600, Q = 17, and B = 200), respectively.
Temporal compression tries to compress across many frames of video over time, recording only differences between each frame rather than each actual frame.
The MPEG2 standard defines a "professional profile" that uses spatial and temporal compression to achieve video compression.
