What is the difference between vector quantization and scalar quantization?
In scalar quantization, a scalar value is selected from a finite list of possible values to represent a sample. In vector quantization, a vector is selected from a finite list of possible vectors to represent an input vector of samples.
What are the advantage of vector quantization over scalar quantization?
Answer. 1) it can reduce the number of reconstruction level when D is held constant. 2) vector quantization can lower the average distortion D with number of reconstruction level held constant.
Which statement is correct for scalar quantization and vector quantization?
(11) What statement is correct for comparing scalar quantization and vector quantization? a. By vector quantization we can always improve the rate-distortion performance relative to the best scalar quantizer.
What is meant by vector quantization?
Vector quantisation (VQ) is the assignment of one code word to a group of two or more picture elements. Compression is achieved through the number of available code words being less than the number of permutations of the possible values of the input pels in the group.
