http://latex.codecogs.com/gif.latex?H'_{i+1}(x,y)=round(\frac{H_{i}(2x-1,2y-1)+H_{i}(2x,2y-1)+H_{i}(2x,2y)}{4})-H_{i+1}(x,y)

for this equation i wrote this code. x=51; y=52; H2'(x,y)=((H1(2x-1,2y-1)+H1(2x-1,2y)+H1(2x,2y)))/4 P=H2(x,y); Q=H2'(x,y-H2(x,y);

here first of all H represents a horizontal subband of image 128 x 128. from this i'am derive detailed subbands H1,H2,H3. values 51 52,76 76,88 88. "i" values varies from 1 and 2.
