摘要
目前,各种start-of-the-art的人脸检测算法被提出,但是在不断提高精度的同时,却忽略了检测的实时性和可应用性。针对这一问题,提出了一种轻量级、实时性和Single-Stage的高精度人脸检测算法。通过将主干网络的不同尺度的特征输出到对应的检测模块中进行检测,实现不同大小人脸的检测,提高算法精度;主干网络运用深度可分离卷积将传统的3×3卷积核分为一个深度卷积核和1×1卷积核,减少计算量;检测模块中使用特征融合获得更多的上下文信息和更大的感受野,并包含目标分类和框体回归操作;采用全卷积神经网络,减少内存量,并使得网络可以输入不同尺寸的图像。实验结果表明,算法在FDDB数据集上有着93.52%的准确率,同时在不同尺度、姿态、装扮和光照等环境下具有较好的鲁棒性,并且能够达到实时检测。
At present,various start-of-the-art face detection algorithms have been proposed,but while continuously improving the accuracy,the real-time and applicability of detection have been neglected.Aiming at this problem,we propose a lightweight,real-time and Single-Stage high-precision face detection algorithm.We input different scale features of the backbone network into different detection modules to realize the detection of different size faces and improve the detection accuracy of the algorithm.The backbone network uses the deep separable convolution to divide the traditional 3×3 convolution kernel into a deep convolution kernel and a 1×1 convolution kernel,reducing the amount of computation.The detection module uses feature fusion for more contextual information and greater receptive fields,including target classification and box regression operations.In addition,we use a full convolutional neural network to save memory and enable the network to input images of different sizes.The experiment shows that the proposed algorithm has 93.52%accuracy in FDDB dataset and better robustness in different scales,poses,dressing and illumination,which can achieve real-time detection.
