Quantization's the procedure of constraining something from a continuous set of values (such as the real numbers) to a discrete set (such as the integers). Quantization in specific domains's discussed in: Quantization (signal processing) Quantization (image processing) Quantization (sound processing) Quantization (music) Quantization (physics) Canonical quantization Spatial quantization Charge quantization Quantization (linguistics) Similar term: Quantification… (More on Quantisation)
