摘要:

最近开发的马面部动作编码系统(EquiFACS)提供了一个精确和详尽的,但费力的,手动标记方法的面部动作单位的马。为了自动化这个过程的一部分,我们提出了一种基于深度学习的方法来自动从图像中检测EquiFACS单元。我们使用级联框架;我们首先训练多个目标检测器来检测预定义的感兴趣区域(ROI),然后对相关区域中的每个动作单元应用二进制分类器。我们使用常规CNN和从人类面部动作单元识别转移的更定制的模型进行实验。有希望的初步结果,提出了九个行动单位的眼睛和下面部区域。该项目的代码是公开的。

英文摘要:

The recently developed Equine Facial Action Coding System (EquiFACS) provides a precise and exhaustive, but laborious, manual labelling method of facial action units of the horse. To automate parts of this process, we propose a Deep Learning-based method to detect EquiFACS units automatically from images. We use a cascade framework; we firstly train several object detectors to detect the predefined Region-of-Interest (ROI), and secondly apply binary classifiers for each action unit in related regions. We experiment with both regular CNNs and a more tailored model transferred from human facial action unit recognition. Promising initial results are presented for nine action units in the eye and lower face regions. Code for the project is publicly available.
