To solve the time redundancy of FPD gray scale imaging process,the fractal principle is firstly applied to the FPD scanning system in this paper,and the optimal scanning architecture is educed and its fractal model is proposed.
Generally there are three kinds of resource redundancy in Fault-tolerance that are hardware redundancy, software redundancy, time redundancy and information redundancy.
Using these methods we can choose one from these multi-image, which reduces the amount of data that put into cloud image database in a sense and solves the problem of time redundancy of cloud image database.
Motion estimation is one of the most important part of motion compensation/DCT based hybrid video coding standards which lead to high compression ratio by efficiently reducing temporal redundancy between adjacent frames of video sequence.
In the proposed algorithm, first, fine tuned motion estimation of H.263 is used to reduce temporal redundancy, and exhaustive overlapped block motion compensation is used to ensure the coherency in motion compensation error frames.
First,according to the weakness of the motion compensated lifting(MCLIFT) scheme and the characteristic of MPEG,a new frame structure is used in frame to frame filtering to wipe off temporal redundancy. Then,2-D spatial wavelet decomposition is used in each frame,and the wavelet coefficients are encoded with SPIHT algorithm.
A scheme of variable block size Multiresolution Motion Estimation(VBMRME) is presented in this paper,which reduces temporal redundancy between pictures of the image sequence. Motion vectors in the highest level of the wavelet pyramid are first estimated.
In order to remove interframe redundancy and thus to achieve high compression ratio, motion estimation algorithm is used to produce a prediction of a frame to be coded from previously coded reference frames. Quick search speed and high precision are essential to shorten coding time, heighten compression ratio and improve image quality.
Block-based motion estimation is the key technique of video coding which can reduce the temporal redundancies of sequences to make compression efficient.

An important probabilistic-time characteristic of the performance of technical systems with structural and time redundancy is derived in terms of Laplace transform.
A τ-decomposition method for monitoring a control automaton with time redundancy
We consider a queueing system consisting of unreliable processors with hardware, information, and time redundancy.
The correctness of every instruction is confirmed by multiple execution instances through a hybrid hardware-time redundancy approach.
Schizophrenics could be separated from depressed psychotics by their inability to utilize temporal redundancy to speed up saccade initiation on the SIS task.
The method employs a pseudo-YUV color space and criteria to detect temporal redundancy and low spatial frequency regions.
Such a design can eliminate temporal redundancy and is therefore, economically more efficient.
Motion estimation has always been an important part of video encoding systems because it can reduce temporal redundancy effectively and thus has significant impact on the bit rate and the output visual quality of the encoded sequence.
The hybrid coder uses vectorgraph coding to remove spatial redundancy of the key frames and motion parameter coding to reduce the temporal redundancy of the OOSs.
