Figure 3: Setup for regions shown in Figure 2
Example 2 : Advanced Motion Map
The motion map may show macroblocks outside the range of interest. This example
demonstrates how the motion map works. In short, only those macroblocks inside the defined
areas of interest will show motion. Some macroblocks outside the region of interest may show
motion. These should be ignored.
In this example, a small motion detec tion region in the upper left corner is produced as shown
in Figure 4.
