Urgent! ! ! What does "vector quantization" mean

1. In mathematics and physics, a quantity with both magnitude and direction is called a vector (also called a vector), which quantifies the definition of scientific terms relative to a scalar.

2. Chinese name: Quantification English name: Quantitative Quantization Definition 1: The process of converting the continuously changing analog or density values of image samples into discrete digital sample values. Discipline: Surveying and Mapping (first-class discipline); Photogrammetry and Remote Sensing (two disciplines) Definition 2: The process of dividing the continuous range of an analog signal value into several adjacent intervals with unique magnitude, and all the sampled signal samples falling in an interval are designated as the magnitude of the interval. Discipline: communication technology (first-class discipline); Communication principle and basic technology (two disciplines)
