Digital Image Processing

A continuous image is digitised at ___________points.

• random

• vertex

• contour

• sampling

The transition between continuous values of the image function and its digital equivalent is called

• Quantisation

• Sampling

• Rasterisation

• None of the Mentioned

Images quantised with insufficient brightness levels will lead to the occurrence of
