Quantization in image processing refers to the process of mapping a continuous range of values to a finite range of discrete levels. This is often applied to pixel values in digital images, where continuous color or intensity values are rounded to the nearest predefined levels. This process reduces the amount of data needed to represent an image, enabling compression and efficient storage, but can also lead to loss of detail and introduce artifacts if not done carefully.

What is digital image processing?
Image processing is the method of processing data in the form of an image. Image processing is not just the processing of image but also the processing of any data as an image. It provides security.
Classification or types of image processing?
Image Processing classify as three type. (1) Low level image processing (noise removal, image sharpening, contrast enhancement) (2) Mid level image processing (segmentation) (3) High level image processing (analysis based on output of segmentation)
Hardwares used in image processing?
The signal processing hardware can be used for image processing also. DSP processors like TMS 6713 can be used in image processing also. The hardware is required for image capture also.
What is image acquisition in image processing?
Its name specifies definition. To get image from any source especially hardware based any source is called as image acquisition in the image processing because without image receiving/acquisition, the processing on the image is not possible. It is the first step in the workflow.
What are the types of image processing?
there are two types of image processing. 1.analog 2.digital.
What are the goals of signal processing?
Signal processing's goals include many things, most importantly: sampling, quantization, noise reduction, image enhancement, image understanding, speech recognition, and video compression.

What is quantization range?
Quantization range refers to the range of values that can be represented by a quantization process. In digital signal processing, quantization is the process of mapping input values to a discrete set of output values. The quantization range determines the precision and accuracy of the quantization process.
What is the relationship between quantisation noise and bandwidth in pcm systems?
Quantization noise is a model of quantization error introduced by quantization in the analog-to-digital conversion(ADC) in telecommunication systems and signal processing.

What is a process image?
image processingIn electrical engineering and computer science, image processing is any form of signal processing for which the input is an image, such as photographs or frames of video; the output of image processing can be either an image or a set of characteristics or parameters related to the image. Most image-processing techniques involve treating the image as a two-dimensional signal and applying standard signal-processing techniques to it.
Hardwares used in image processing?
The signal processing hardware can be used for image processing also. DSP processors like TMS 6713 can be used in image processing also. The hardware is required for image capture also.
What is analog image processing?
In electrical engineering and computer science, analog image processing is any image processing task conducted on two-dimensional analog signals by analog means (as opposed to digital image processing).
What is meant by quantization?
In physics, quantization is the process of explaining a classical understanding of physical phenomena in terms of a newer understanding known as "quantum mechanics". It is a procedure for constructing a quantum field theory starting from a classical field theory. In digital signal processing, quantization is the process of approximating ("mapping") a continuous range of values (or a very large set of possible discrete values) by a relatively small ("finite") set of ("values which can still take on continuous range") discrete symbols or integer values. In digital music processing technology, quantization is the process of aligning a set of musical notes to a precise setting. This results in notes being set on beats and on exact fractions of beats. Quantization, involved in image processing, is a lossy compression technique achieved by compressing a range of values to a single quantum value. When the number of discrete symbols in a given stream is reduced, the stream becomes more compressible. In linguistics, a quantized expression is such that, whenever it is true of some entity, it is not true of any proper subparts of that entity. Example: If something is an "apple", then no proper subpart of that thing is an "apple".
What is blocking artifact in image processing?
Blocking artifacts in image processing refer to visible distortions that occur when an image is compressed using block-based methods, such as JPEG compression. These artifacts manifest as blocky patterns or sharp edges, especially in areas of uniform color or subtle gradients, due to the quantization of pixel values within small blocks. They become more pronounced at higher compression levels, where information loss is greater. Effective techniques to mitigate blocking artifacts include using advanced compression algorithms or post-processing methods like filtering.
