1- In image restoration process, the degraded image in frequency domain
G(U,V) is defined as:
G(U,V) = H(U,V)F(U,V)+N(U,V)
1- Depict the degradation model
2-A blur filter of 2x2 size has h(0,0) = 8, h(1,0) = 5, h(0,1) = 7, h(1,1) = 4 represents
a motion blur of an object. For the location (0,0) of the blur filter, calculate the
following:
a- the discrete Fourier transform DFT at this location.
b- calculate the magnitude, in frequency domain, for both the inverse filter
and wiener filter at this location if St (0, 0)= 0.7 and SN(0, 0)=0.01.
