Age Estimation from Facial Photos: A CNN-Based Approach with Multi-Model Feature Fusion

Abstract

This study was designed to improve the accuracy and efficiency of facial age recognition by training and tuning advanced deep learning models. This study evaluated the performance using the UTK Face dataset and multiple deep learning models for the facial age recognition task and found that a three-model fusion (EfficientNetB0, DenseNet121, and Inception V3) had the best accuracy and generalization ability. The study also tried adding a Transformer layer, but the results were not significantly improved. Triple Model Fusion (EfficientNetB0, DenseNet121, and Inception V3) with the addition of the Transformer layer had an overall accuracy of 64%, which was slightly lower than the version without the Transformer (65% accuracy). Triple Model Fusion performed in all tested configurations Best with 65% accuracy.
