Face Recognition System Based on MATLAB R2008

A face recognition system developed using MATLAB R2008 that implements two distinct algorithms: PCA+Adaboost and PCA+SVM, utilizing the ORL face database. The system achieves 84% recognition accuracy by processing a single facial image to identify individuals, demonstrating efficient feature extraction and classification through principal component analysis combined with ensemble learning and support vector machine methods.

Single-Phase Three-Level Inverter with SPWM Control

This novel single-phase three-level inverter configuration combines one three-level bridge arm with one conventional bridge arm, utilizing Sinusoidal Pulse Width Modulation (SPWM) control. The MATLAB 2008 implementation includes power electronics modeling, modulation index configuration, and output waveform analysis through Simulink blocks and signal processing functions.
