Solution:

Image sampling Quantization:

Digitizing intensity values.

The sampling rate decider spatial resolution while quantization levels determine the no. of gray levels in the digitized ing.

The no. of quantization levels should be high enough for human perception of fine shading details in the image. The occurrence of false contours is the main problem In an image that has bile quantized with Insufficient brightness levels.

Values representing the time intervals are rounded off to create a defined set of possible amplitude values.
