基于深度残差网络和注意力机制的人脸检测算法

人脸检测技术作为一种人员身份识别的主流技术被广泛应用于人们的日常生活中。然而在特定应用场景中，当人脸被遮挡或人脸目标非常密集时，人脸识别的检测性能急剧下降。提出一种基于深度残差网络和注意力机制的高精度人脸检测算法。使用残差网络ResNet-50并结合IoU损失函数提高人脸检测精度，并利用注意力机制优化突出脸部区域特征，在此基础上采用非极大值抑制方法增强算法鲁棒性。在公开FDDB数据集上的实验结果表明，该算法的准确率达到96.1%相比传统卷积网络VGG-16算法提高1.6个百分点。

Face Detection Algorithm Based on Deep Residual Network and Attention Mechanism

As a mainstream technology for personal identification,face detection has been widely used in daily life. However,in some application scenarios,the face recognition performance will be decreased dramatically when the face is occluded or the face targets are very dense.To address the problem,a high-precision face detection algorithm based on deep residual network and attention mechanism is proposed.The algorithm utilizes the residual network ResNet-50 combined with the IoU loss function to improve the accuracy of face detection,and then the attention mechanism is employed to optimize the prominent facial area features.On this basis,the Non-Maximum Suppression(NMS) method is used to enhance the robustness of the algorithm.The experimental results on the public dataset,FDDB,show that the accuracy rate of the proposed algorithm reaches 96.1%,which is 1.6% higher than that of the traditional algorithm based on VGG-16.
