Human age can be employed in many useful real-life applications, such as customer service systems, automatic vending machines, entertainment, etc. In order to obtain age information, image-based age estimation systems have been developed using information from the human face. However, limitations exist for current age estimation systems because of the various factors of camera motion and optical blurring, facial expressions, gender, etc. Motion blurring can usually be presented on face images by the movement of the camera sensor and/or the movement of the face during image acquisition. Therefore, the facial feature in captured images can be transformed according to the amount of motion, which causes performance degradation of age estimation systems. In this paper, the problem caused by motion blurring is addressed and its solution is proposed in order to make age estimation systems robust to the effects of motion blurring. Experiment results show that our method is more efficient for enhancing age estimation performance compared with systems that do not employ our method.
人类年龄可应用于许多实际生活中的有用场景,如客户服务系统、自动售货机、娱乐等。为了获取年龄信息,已开发出基于图像的年龄估计系统,利用人脸信息进行年龄估计。然而,由于相机运动、光学模糊、面部表情、性别等多种因素,当前的年龄估计系统存在局限性。运动模糊通常会因相机传感器的移动和/或图像采集过程中人脸的移动而出现在人脸图像上。因此,捕获图像中的面部特征会根据运动程度发生变化,这会导致年龄估计系统的性能下降。本文针对运动模糊引起的问题进行了探讨,并提出了解决方案,以使年龄估计系统对运动模糊的影响具有更强的鲁棒性。实验结果表明,与未采用我们方法的系统相比,我们的方法在提高年龄估计性能方面更有效。
