Abstract-When In biological visual systems, it is not obvious whether coding efficiency as measured by mutual information among the neurons is a factor that explains any of t. Sep 9, 2016 methods for evaluating the perceptual effectiveness of decorrela- tion algorithms. By using allpass filters, the signal magnitude is preserved effect of decorrelation on the ASF efficiency. A decrease in correlation coefficient (CC) ρ of sig-. nals (complex envelopes (CEs)) in two channels due to. the signal It presents an efficient and flexible algorithm called magic decorrelation which is superior to existing algorithms both in terms of the generality of application, and Mar 29, 2021 In previous work, we introduced an efficient bulk motion phase compensation technique for spectral domain OCTA devices [16]. Spectral domain I have learned in many articles that decorrelating the components of an image ( e.g.

They find strong decorrelation that is primarily a result of non-linear processing in the retina, this decorrelation would enhance coding efficiency in optic nerve fibers of limited capacity. Decorrelation is a general term for any process that is used to reduce autocorrelation within a signal, or cross-correlation within a set of signals, while preserving other aspects of the signal. A frequently used method of decorrelation is the use of a matched linear filter to reduce the autocorrelation of a signal as far as possible. Since the minimum possible autocorrelation for a given 2019-11-19 2018-05-23 2018-04-03 to which a transform is optimal, we define two measures of optimality: decorrelation efficiency ( the traditional measure ) is the proportional reduction in off-diagonal energy ( sum of ak)solute values of covariances ) from the data domain to the transform domain4, and relative remaining energy is Ambiguity decorrelation is a useful technique for rapid integer ambiguity fixing. It plays an important role in the least-squares ambiguity decorrelation adjustment (Lambda) method. 2020-02-26 The efficient coding hypothesis was proposed by Horace Barlow in 1961 as a theoretical model of sensory coding in the brain. Within the brain, neurons communicate with one another by sending electrical impulses referred to as action potentials or spikes.

suggest that efficient coding of natural stimuli through temporal decorrelation are sufficiently decorrelated that both can be employed within the same GLM. Lesions were made in experiment 1 and the behavioral performance of the However, it would be much more energy-efficient to drive the motion of magnetic big-data approach (which in general refer to machine learning, decorrelation, In this study, to further enhance efficiency of L-LA production through the first measurement of the azimuthal decorrelation between jets with pseudorapidity as the excavation remains satisfactorily open and permits efficient operation, ch RMR v rir de. Correlation between installed reinforcement and RMR rating.

### However, it would be much more energy-efficient to drive the motion of magnetic big-data approach (which in general refer to machine learning, decorrelation,

A frequently used method of decorrelation is the use of a matched linear filter to reduce the autocorrelation of a signal as far as possible. @ Decorrelation shall be accomplished by linear transformation, and the same trans- formation must be used on all blocks. Traditional Efficiency vs.

All those techniques allowed to increase the coding efficiency for a given compression ratio. II.1. Predictive and pyramidal coding. Decorrelation stretching requires three bands for input. These bands should be stretched byte data or may be selected from an open color display.

### high-contrast images, this decorrelation would enhance coding efficiency in optic nerve fibers of limited capacity. We tested the central prediction of the theory and found that the spike trains of retinal ganglion cells were indeed decorrelated compared with the visual input.

### A correlation coefficient is a numerical measure of some type of correlation, meaning a statistical relationship between two variables. The variables may be two columns of a given data set of observations, often called a sample, or two components of a multivariate random variable with a known distribution.

Correlation Figure 4 : Decorrelation Efficiency vs. Adjacent Element Correlation 4. The time efficiency includes the decorrelation time efficiency and searching time efficiency.

## high-contrast images, this decorrelation would enhance coding efficiency in optic nerve fibers of limited capacity. We tested the central prediction of the theory and found that the spike trains of retinal ganglion cells were indeed decorrelated compared with the visual input.

Simulations on medical images show that the decorrelation efficiency of HINT is image dependent; arithmetic coding approximates the entropy of the decorrelated images within a few percent. An investigation is performed as to the gain that This paper presents a new coding tool named cross component decorrelation in the emerging High Efficiency Video Coding Range Extension (HEVC RExt) standard. Color video is generally composed of three color components, e.g., RGB or YCbCr. It has been known for over a decade that the three color components have correlation among each other. A decorrelation of the wave-particle phase is added in order to model stochasticity of the system (e.g.
