In this lecture notes, we will review the main concepts and results of scalar and vector quantization. For more details, see the book by Gersho and Gray [2], the accessible tutorial by Gray [3], or the comprehensive review by Gray and Neuhoff [4]...
Vector quantization (VQ) is a generalization of scalar quantization to the quantization of a vector, an ordered set of real numbers. The jump from one dimension to multiple dimensions is a major step and allows a wealth of new ideas, concepts, techniques, and applications to arise that often...

A vector quantization library originally transcribed from Deepmind's tensorflow implementation, made conveniently into a package. It uses exponential moving averages to update the dictionary. VQ has been successfully used by Deepmind and OpenAI for high quality generation of images (VQ-VAE-2) and mus...
Generally speaking, two kinds of quantization methods can be distinguished, based on uniform and adaptive quantizers. Moreover, quantization can operate on scalar or vector data samples, referred to as scalar quantization (SQ) and vector quantization (VQ), respectively. Uniform scalar quantization The...
Scalar-vector quantization of medical images A new coding scheme based on the scalar-vector quantizer (SVQ) is developed for compression of medical images. The SVQ is a fixed rate encoder and its rate... Mohsenian,N.,Shahri,... - 《IEEE Transactions on Image Processing》 被引量: 3发表:...
Such quantization results in an existence surface in the three-dimensionalparameter space of Kerr–Newman black holes. The phenomenology of stationary scalarclouds has been widely addressed over the last years. However, there is a gap in the liter-ature concerning their vector cousins. Following the...
whereas in vector quantization blocks of source output are quantized. Scalar quantizers can be further classified asuniform quantizersandnonuniform quantizers.In uniform quantization, the quantization regions are chosen to have equal length; in nonuniform quantization, regions of various lengths are allo...
Contains configuration options specific to the scalar quantization compression method used during indexing and querying.
A digital color image quantization mechanism employs sequential product code vector quantization, to sequentially extract chrominance and luminance values from the vectors and quantizes chrominance an
