Suppose we use N=2 i.e. 2x2 tiles shown below:

[ [1,0],

[1,0] ]

a) Calculate DC value and DCT value F(0,1) for the image

b) How many basis images are there?

c) State the formula above for F(u,v) for the special case of M=N=2

d) Write down the basis image values

e) Draw the basis images; briefly explain what you do in order to show these images.
