A proper estimate of the histogram of the absolute difference between the image of the table only from the other image to produce an unshaded picture of the ball setup prior to the last shot is:

a$.$ H $=[010030070070060050060050040040060050020000]$

b$.$ H$=[010040070080060050060050040040060040010000]$

c$.$ H$=[00100000000000100100000]$

d$.$ H$=[0010000000000010010000]$

e$.$ None of the above
