Image Sampling vs Quantization - GeeksforGeeks
2024年7月1日 · This article delves into the definitions, processes, and differences between image sampling and quantization. What is Image Sampling? Image sampling is the process of converting a continuous image (analog) into a discrete image (digital) by selecting specific points from the continuous image.
Quantization (signal processing) - Wikipedia
Quantization, in mathematics and digital signal processing, is the process of mapping input values from a large set (often a continuous set) to output values in a (countable) smaller set, often with a finite number of elements. Rounding and truncation …
Fundamental Concepts: Sampling, Quantization, and Encoding
Quantization comes after sampling as a crucial step in converting continuous analog signals to digital signals. A continuous set of values (like voltage levels) is quantized into a discrete set of values.
Image Processing: Sampling and Quantization - Baeldung
2024年3月18日 · In this tutorial, we briefly discussed image processing as well as explored sampling and quantization concepts. In addition, we also highlighted some of the key advantages and popular applications of digital images.
Chapter 20: Analog to Digital Conversion [Analog Devices Wiki]
An ADC carries out two processes, sampling and quantization. The ADC represents an analog signal, which has infinite resolution, as a digital code that has finite resolution. The ADC produces 2N digital values where N represents the number of binary output bits.

Sampling and Quantization in Digital Image Processing
2024年4月12日 · We'll discuss how image sampling involves capturing discrete samples of an image's continuous spatial domain, while quantization focuses on reducing the number of colors or intensity levels in an image.
The process of digitizing the domain is called sampling and the process of digitizing the range is called quantization. Most devices we encounter deal with both analog and digital signals. Digi-tal signals are particularly robust to noise, and extremely efficient and versatile means for processing digital signals have been developed.
