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

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
