Question 1: In the image compression we use three different methods to compress pixel data:
a) Mapping the pixel values to some other set of values.
b) Quantizing those values.
c) Symbol encoding the resultant values.
Describe each method; describe the manner in which it helps us to compress the image, and explain how the method is implemented in the baseline JPEG compression method.
Question 2: Explain the limitations of human vision in terms of:
a) Spatial resolution
b) Luminance
c) Color
and describe the implications that each of these has on the design of display devices, comprising numerical estimates of the limits beyond which a human can’t discriminate.
