Figure 5

Distance distributions between the test images and the templates. X axis represents different persons (i.e., class ID) while Y axis means the distance between a test image and the templates. The blue points (“+”) indicate the distances between the test images and the non-occluded template; green points (“o”) show the distances between the test images and the occluded template; The test images are nonoccluded images (first row) and occluded images (second row). The proposed DCFB framework using the gray, HOG and Gabor features are given in the left column, middle column, and right column, respectively.
