Image Sampling and Quantization in Digital Image Processing
2540 Views • Posted On Sept. 30, 2020
To create a digital image, we need to convert the continuous sensed data into digital form.
This involves two processes: Sampling and Quantization
An image may be continuous with respect to x and y coordinates, and also in amplitude.
To convert it into digital form, we have to sample the function in both coordinates and in amplitude.
Digitizing the coordinate values is called Sampling. Digitizing the amplitude values is called Quantization.
