DEVELOPMENT OF AN ENHANCED CONVOLUTIONAL NEURAL NETWORK (CNN) BASED ON FACIAL RECOGNITION MODEL – A REVIEW

Facial recognition is a critical biometric technology applied in surveillance, access control, and identity verification.However, existing Convolutional Neural Network (CNN) based models often face performance limitations under challenging conditions such as poor lighting, pose variations, occlusion, and facial expression changes.This study proposes a robust and adaptive CNN architecture to enhance recognition accuracy and generalization.The research objectives are to (i) review existing CNN based models, (ii) design an improved CNN architecture, (iii) implement and train the model using standard datasets, (iv) evaluate its performance using accuracy, precision, recall, and F1 score, and (v) compare results with baseline CNN models.The study adopts a quantitative methodology using Python based deep learning frameworks.Pre collected datasets including Labeled Faces in the Wild (LFW), CelebA, and UTKFace are processed using image normalization, face alignment via MTCNN, and data augmentation.Statistical performance metrics and confusion matrix visualization support comprehensive performance evaluation.While results demonstrate improvements, limitations include computational cost, dataset diversity, and real world deployment challenges such as latency and adaptability in dynamic environments.
