1. Look at example 3.2 on page 44 of your textbook (second edition). This program is used for bit level slicing. Make the following_change to the code given to you already in the book: Apply it to the image p_1_4_a.jpg (the picture of a lady "Lena") instead of 2.jpg Instead of slicing the last 4 bits, slice off the last three bits (k(6) = 0, k(7) = 0, k(8) = 0) Now Instead of slicing the last 4 bits, slice off the last 5 bits. Make sure to include your name in the script. Print out the Script, the Original Image and the Final Image (with 3, 4 and 5 bits sliced off). What difference do you observe? I=imread ('2.jpg'); I=rgb2gray (I); imshow (I, [O 255]) ; S=size (I); I=double (I); I=dec2base (1,2); newS=size (I); J= zeros (S(1),s(2)); for I = 1:news (1) k=char (I(i, :)); k (5) = '0'; k(6)='0'; k (7)='0'; k (8) = '0'; k=base2dec (k, 2); a=fix (i/s(1) ) +1; b=mod (i,s(1)); if b==0 b=S (1); a=a-1; end J(b, a) =k; end figure, imshow (J, [O 255])
