Hidden Markov Model (HMM)-based face recognition achieves an impressive 90% accuracy rate through probabilistic pattern analysis and sequential feature processing.
A MATLAB implementation of eigenface-based face recognition with comprehensive Chinese annotations, featuring PCA dimensionality reduction, feature extraction, and threshold-based classification algorithms.
This implementation includes two core modules (PCA and LDA) that perform principal component analysis for dimensionality reduction followed by linear discriminant analysis for classification, achieving excellent experimental results in face recognition applications.
Face Recognition System: PCA Feature Extraction Followed by Neural Network Classification
The system consists of the following components: capturing images using a computer's built-in camera, face detection, storing detected face images in a database, and performing face recognition using input photos. This program implements face detection through a skin color recognition approach, where the facial skin color range is defined as 100≤B≤120 and 140≤R≤160. Pixels within this range are set to white while the remaining pixels are set to black. The algorithm employs the imerode function for spherical erosion and applies median filtering to achieve smoothing effects. Finally, after scaling, binarization, and various processing stages, regions with fewer than 1000 white pixels are discarded. Image segmentation incorporates Euler numbers to eliminate background areas resembling facial colors.
