FAST feature point extraction algorithm: (a) is the selected corner point, and a Bresenham circle is established around the point . The face image is from FF++ [18]. (b) Simplified corner operations. The face image is from FF++ [18]. (c) Fast corner points detection in eight regions. The face image is from FF++ [18].
