Reading RGB Image Original Grayscale Image A=A(448)
448 by 794 matrix, rank(A)=448
A(10): the best approximation by matirices of rank 10 A(40): the best approximation by matirices of rank 40
A(70): the best approximation by matirices of rank 70 A(100): the best approximation by matirices of rank 100
