The soft-decision quantization includes first performing hard-decision quantization to obtain hard quantized coefficients and, then, obtaining a soft quantized coefficient using a rate-distortion calculation over a search range of quantization levels for a transform domain coefficient, wherein the search ...
This example shows how to quantize the learnable parameters in the convolution layers of a deep learning neural network that has residual connections and has been trained for image classification with CIFAR-10 data. Quantize Layers in Object Detectors and Generate CUDA Code ...
Vector quantization is alossy datacompression method. It works by dividing a large set of vectors into groups having approximately the same number of points closest to them. Each group is represented by its centroid point, as in k-means and some other clustering algorithms...
Traditional compression algorithms have been centered on reducing redundancies in data sequences –be it in images, videos, or audio– with a high reduction in file size at the cost of someloss of informationfrom the original. The MP3 encoding algorithm significantly changed how we store and shar...

Although quantization in the information theory literature is generally considered as a form of data compression, its use for modulation or A/D conversion was originally viewed as data expansion or, more accurately, bandwidth expansion. For example, a speech waveform occupying roughly 4 kHz would ...
Basic Compression Tools 3.2 Quantization The quantization step is a lossy process which reduces the precision of the data samples into a discrete set of levels. The general quantization process is shown in Fig. 3.2. Sign in to download full-size image Figure 3.2. Quantization process: Q represen...
