ABSTRACT
Any analog quantity that is to be processed by a digital computer or digital system must be converted to an integer number proportional to its amplitude. The conversion process between analog samples and discrete-valued samples is called quantization. The following section includes an analytic treatment of the quantization process, which is applicable not only for images but for a wide class of signals encountered in image processing systems. Section 5.2 considers the processing of quantized variables. The last section discusses the subjective effects of quantizing monochrome and color images.
