Sentence examples for during quantization from inspiring English sources
One of the most important issues in the design and operation of a quantizer is the distortion metric used in codebook generation and codeword selection from codebooks during quantization.
The last subcategory of unsupervised biometric discretization, known as equal-probable quantization-based discretization [14] segments each single-dimensional feature space into multiple non-overlapping equal-probable intervals, whereby every interval is constructed to encapsulate an equal portion of background probability mass during quantization.
On the other hand, the unsupervised equal width quantization-based discretization [12, 13] partitions each single-dimensional feature space into a number of non-overlapping equal-width intervals during quantization in accordance with the quantity of bits required to be extracted from each dimension.
A typical steganographic application is the perturbed quantization [16]; during quantization process, for example, JPEG compression, real values have to be rounded between possible quantized values ; when lies close to the middle of an interval, one can choose between and without adding too much distortion.
On the other hand, CSI inaccuracies also result from the delay of the feedback path, leading to a mismatch of the CSI experienced during the quantization phase and the CSI valid during transmission.
Note that the scale of the signal has been lost during the quantization process.
In certain situations, the underlying source distribution or the distortion function of the source variable varies during the quantization process.
Toe fourth column considers the average utility function and its standard deviation over all the cells.
Since each node consider only the information available to it during quantizer design, there will still exist much redundancy after quantization which the merging technique can attempt to reduce.
Face image is vulnerable to noises during its acquisition, quantization, compression, and transition.
In the proposed method, the loss occurs only during the vector quantization process.
