the first step in digital image processing is

the process that assigns a label
to an object based on the information provided
by its descriptors

assigning meaning to an
ensemble of recognized objects

make a decision on how the
extracted data should be represented

Improving appearance of
an image. Tend to be based on mathematical or
probabilistic models of image degradation

Bring out detail or highlight certain features of
interest

Judge the enhancement results according to human
subjective preferences

Color is a powerful descriptor that often
simplifies object identification and extraction
from a scene

Morphological Image Processing:
Mathematical morphological operations
Tools for extracting image components that are useful in the representation and description of shapes

Partition an image into its constituent parts of objects

Reduce the storage required to save an image
Reduce the bandwidth required to transmit it

Image Sensors contain Physical Device & Digitizer
