Sentence examples for by quantization errors of from inspiring English sources

Thus, with the perceptual characteristics of JND, if the spatial distortion caused by quantization errors of spatial parameters can be limited below the JND thresholds, then the quantization is almost perceptual lossless.

If the spatial distortion caused by quantization errors of spatial parameters can be limited below, the correlated JND threshold, then the quantization can be regarded as nearly perceptual lossless.

The proposed scheme is an improved approach, which is robust to the channel uncertainties caused by quantization errors and the lack of channel quality information (CQI).

This model is applicable when the CSIT error is dominated by quantization errors.

In existing image analysis-based tools, precision at the finest scales is limited by the skeletonization methods used and by quantization errors.

By Theorem 1, it implies that the mean quantization errors of all users on each subcarrier n are identical, v k, n = v k', n.

In [3], quantization matrices for the use in DCT-based compression were designed by exploiting visibility thresholds that are experimentally measured for quantization errors of the DCT coefficients.

Quantization errors of azimuths coincided with azimuthal JND curve means nearly perceptual lossless quantization.

Second, we assume that half of the reconstruction error of each signal is induced by the quantization error of the perceptual quantizer and the other is induced by the prediction error from the preprocessed signals.

As illustrated in Figure6, the combined user selection algorithms outperform the clustered S-best criterion by reducing the quantization error of the CDI with the usage of the proposed codebook design.

The technique concentrates on reducing the quantization error of the quantized vectors by "blowing out" the residual quantization errors with an LVQ scale factor.
