P-frame coding in H.264 uses Integer Transform. For this exercise, assume: 1 -2 F(u, v) - H f(i,j) - H', where H - 1 -2 2 (a) What are the two advantages of using Integer Transform? (b) Assume the Target Frame below is a P-frame. For simplicity, assume the size of macroblock is 4 x 4. For the macroblock shown in the Target Frame: What should be the Motion Vector? (ii) What are the values of f(Lj) in this case? (iii) show all values of F(u, v) 20 40 60 80 100 120 140 155 30 50 70 90 110 130 150 165 40 60 80 100 120 140 160 175 50 70 90 110 130 150 170 185 60 80 100 120 140 160 180 195 70 90 110 130 150 170 190 205 80 100 120 140 160 180 200 215 85 105 125 145 165 185 205220 110 132 154 176 120 142 164 186 130 152 174 196 140 162 184 206 Reference Frame Target Frame
