To create a digital image, we need to convert the continuous sensed data into digital form.
This process includes 2 processes:
- Sampling: Digitizing the co-ordinate value is called sampling.
- Quantization: Digitizing the amplitude value is called quantization.
To convert a continuous image f(x, y) into digital form, we have to sample the function in both co-ordinates and amplitude.
Difference between Image Sampling and Quantization:
