Linear Discriminant Analysis Algorithm with Face Recognition Implementation

This implementation utilizes the Linear Discriminant Analysis (LDA) algorithm, a supervised dimensionality reduction technique that projects data onto a lower-dimensional space while preserving class discriminatory information. The compressed package contains substantial datasets of training and test images specifically formatted for facial recognition experiments, featuring preprocessing routines for image normalization and feature extraction. The core algorithm calculates within-class and between-class scatter matrices to determine optimal projection vectors that maximize class separation. Beyond facial recognition, the LDA framework can be extended to other pattern recognition domains such as speech signal processing through appropriate feature engineering. The codebase includes key functions for eigenvalue decomposition, projection matrix computation, and classification boundary determination.
