There are three types of sampling methods in Image Processing:

##### Ideal Sampling

In ideal sampling (Instantaneous sampling) pulses from the analog signal are sampled. This is an idea sampling method and cannot be easily implemented.

##### Natural Sampling

Natural sampling is a practical method of sampling in which pulse have finite width equal to T. The result is a sequence of samples that retain the shape of the analog signal.

##### Flat Top Sampling

In comparison to natural sampling, flat top sampling can be easily obtained. In this sampling technique, the top of the samples remains constant by using a circuit. This sampling method is commonly used.
