论文摘要
狗主人通常能够识别出揭示其狗的主观状态的行为提示，例如疼痛。但是自动识别疼痛状态非常具有挑战性。本文提出了一种基于视频的新型，两流深的神经网络方法，以解决此问题。我们提取和预处理身体关键点，并在视频中计算关键点和RGB表示的功能。我们提出了一种处理自我十分和缺失关键点的方法。我们还提出了一个由兽医专业人员收集的独特基于视频的狗行为数据集，并注释以进行疼痛，并通过拟议的方法报告了良好的分类结果。这项研究是基于机器学习的狗疼痛状态估计的第一批作品之一。
Dog owners are typically capable of recognizing behavioral cues that reveal subjective states of their dogs, such as pain. But automatic recognition of the pain state is very challenging. This paper proposes a novel video-based, two-stream deep neural network approach for this problem. We extract and preprocess body keypoints, and compute features from both keypoints and the RGB representation over the video. We propose an approach to deal with self-occlusions and missing keypoints. We also present a unique video-based dog behavior dataset, collected by veterinary professionals, and annotated for presence of pain, and report good classification results with the proposed approach. This study is one of the first works on machine learning based estimation of dog pain state.
