级联深度卷积神经网络(DCNN)算法为首先在人脸关键点检测中使用卷积神经网络(CNN)的模型,CNN的使用使得检测精度得到极大的提升。针对该策略需要对相邻阶段间的数据反复进行回归处理使得算法流程十分复杂的问题,提出基于非对称卷积−压缩激发−次代残差网络(AC-SE-ResNeXt)的人脸关键点检测算法。所提算法仅使用单阶段回归,既避免了级联策略中多阶段回归的算法流程复杂性,又解决了相邻阶段间数据需要进行预处理的问题。为了不降低精度,在次代残差网络(ResNeXt)块的基础上添加了非对称卷积(AC)模块和压缩激发(SE)模块,构建了AC-SE-ResNeXt网络模型。同时,为了能够精确拟合在不同光照、姿态、表情等复杂环境下的人脸,将AC-SEResNeXt网络模型加深到101层。对训练好的模型分别在数据集BioID和LFPW上进行测试,其中该模型在BioID数据集上的人脸五点关键点检测的综合平均误差率为1.99%,在LFPW数据集上的人脸五点关键点检测的综合平均误差率为2.3%。实验结果表明,所改进的算法不但简化了算法流程使之能进行端到端处理,而且其精度与级联DCNN算法相当,鲁棒性也有明显提升。
