  1. With the percentage improvement of GRAB over LBP and V1-like algorithm; this is on FERET240 dataset with gallery and probe images at different scales. The width of the probe images are in pixels in the table. The gallery image size is 130 × 150. Probe and gallery images have the same aspect ratio.
