Face detection has wide applications in biometrics verification and interactive devices that employ human-computer interfaces. The face detection method presented in this book creates a robust yet compact classifier that can be rapidly retrained due to its structure. A new set of features called New Min-Max Analysis (NMMX) that derive horizontal and vertical projections from segmented grayscale image regions. and extracts vertical and horizontal projections from them. Then, a modification of a swarm-based optimization algorithm called Modified Particle Swarm Optimization 1 (MPSO1) was...
