Week 1

Question 1

analog vs digital imaging acquisition

Answer 1

analog:
continous, shades of grey only

digital:
matrix orientation (made of numbers)
discrete

Question 2

Computer numbering system. and how many possible outcomes form a certain bit number is possible

Answer 2

N=2^n
8,4,2,1

e.g if we use 8 bits, then possible grey scale levels are 2^8 = 256

Question 3

what is false contouring

Answer 3

when you don’t have enough bits per pixel i.e not enough shades of grey prevelant)

gives off false edges in colour because of lack of grey scale colouring
