Abstract
To address the issues of insufficient accuracy and significant impact of image noise on model performance in current facial recognition systems, this study proposes a new framework that integrates wavelet transform, an improved multi-task cascaded convolutional neural network (MTCNN), and genetic algorithms (GA). This framework utilizes wavelet transform for image denoising; optimizes MTCNN by introducing a hybrid threshold function and a confidence candidate box retention mechanism to effectively address information loss issues; and applies GA for feature compensation and optimization. Experimental results demonstrate that this method significantly improves the accuracy, recall rate, regression value, and model stability of facial recognition, effectively enhancing the system’s robustness under noise interference, and provides an effective solution for optimizing facial recognition performance.
