人类面部属性估计研究:综述

近年来，人脸属性估计因其广泛的应用而得到了大量的关注和研究，并且很多估计方法被提了出来.主要对现有相关工作进行归纳总结，为研究者提供相关参考.首先，根据是否考虑人脸性别、年龄、人种等不同属性间的内在关联，将现有的人脸面部属性研究方法划分成朴素的研究方法和自然的研究方法这两大类进行总结介绍.然后，从单一人脸数据库标记不完备、现有方法未能完备利用多属性联合估计、现有方法未能很好地利用各面部属性间关系这3个方面阐述当前方法的不足.最后，给出关于人脸面部属性估计进一步的研究方向.

Human Facial Attributes Estimation: A Survey

Over the past decades, human facial attributes (e.g. gender, age, and race) estimation has received large amount of attention and research due to its potential applications, and variety of methods have been proposed to address it. This article is devoted to review related works comprehensively and give references for researchers. Firstly, in accordance with whether exploiting the potential correlations between these facial attributes, the existing approaches are classified into naïve and natural groups and they are reviewed within each group. Then, in terms of incompleteness of annotated labels, considered attributes, and correlations utilization, the drawbacks of existing methods are analyzed. Finally, future research directions are provided at the end of this work.
