5. What is Digital Image
Processing?
• Mathematical operations on the numbers
that make up a digital picture
• Results in a new digital picture which is
different from the original
REMEMBER :
Start with an image -- end with an image

6. Low Contrast Normal Contrast

7. High Noise Low Noise

8. Unnatural Color Realistic Color

9. What is Digital Image Analysis?
• Using the numbers in digital pictures to get
useful information or solve a problem
REMEMBER:
Start with an image -- end with an answer
