Figure 2

Traditional regular face blocks division. This figure illustrates the effect of using different sizes for regular blocks division. It is shown that when there are occlusions on faces, a finer division allows to have more blocks for comparisons (valid areas); meanwhile, in the case of expression variations, a finer division produces a decrease on the recognition rates because small blocks around some face areas, such as mouth and eyes, are shifted to neighbor blocks.
