At the coarse level disparity estimation, most methods suffer from disparity quantization errors
, which cause wrong initialization for the next level, t he boundary blurring is inherent to the multiresolution approaches, which is deteriorated by up sampling processes, which produce better final disparity from multiscale processing, a fusion method that combines multiple intermediate estimates is required.
In these cases, the NGN network can be useful for 3D modeling since their average quantization error
is below this range.
In the case of hardware wavelet-based systems, it is desirable that the quantization error
(Je), The maximum intra-distances (dmax), The minimum inter-distances (dmin) generally are used to analyze and take ideas on segmentation methods
In ND application mean value should be evaluated to achieve suppression of quantization error
Therefore, the performance comparison and the effects of quantization error
for the three data formats are referenced to the estimated speed profile they produce.
Researchers at NIST have developed a new technique for modeling and implementing a method for minimizing the quantization errors
that often accumulate in electronically generated time bases.
For every input [alpha] + [beta] (i + 1/2), both [alpha] + [beta]i and [alpha] + [beta] (i + 1) minimize the quantization error
, and a complete model must provide some basis for choosing between these alternatives.
Subjective perception of quantization error
greatly varies with the frequency and it is advantageous to use coarser quantizers for the higher frequencies.
As a result, there is essentially no quantization error
or non-monotonic behavior, and temperature hysteresis is very low, typically less than 2 mg over the entire 40x C to +175x C temperature range.
The dynamic range of the assumed variance is divided into sub-ranges, and for each of them is designed a separate quantizer whose parameters are set so that the quantization error
is minimal -,
Here, note that q(u(t)) = u(t) + [phi](t), where the kth element of the quantization error
Quantization of the relative coordinates induces quantization error
, see Figure 2.
One noise source at -53 dBm/Hz would provide amplitude and phase tracking calibration, and the other at -143 dBm/Hz would randomize the A/D quantization error
This process necessarily introduces some round-off or quantization error
