摘要
人体行为自动检测技术易受成像角度、环境因素的影响,造成检测准确性下滑,结合单目视觉和深度传感器提出了一种新的行为检测技术。首先筛选出人体行为相关的关键帧,以解决行为速度不统一的问题;结合卷积神经网络特征和幅度直方图作为行为描述符;利用对抗网络实现人体行为的域适应迁移学习,解决单目视觉成像角度偏差的问题。在公开的行为检测数据集上完成了验证实验,结果显示该技术提高了行为检测的性能,并能有效改善单目视觉成像角度差异所导致的检测性能衰减问题。
Body actions automatic detection techniques are usually influenced by imaging angle and imaging environment,these factors lead to detection accuracy reduction,in view of this,a new action detection technique combined monocular vision and depth sensor is proposed.Firstly,the key frames corresponding to body actions are filtered,this process helps to fix the problem of action speed difference;then,the convolutional neural network features and magnitude histogram are combined as action descriptors;finally,adversarial networks are adopted to realize domain adaption transfer learning for body action,in order to solve the problem of imaging anger difference of monocular vision.Validation experiments are carried on a public action detection dataset,and the results of which show that the proposed technique improves action detection performance,and the technique overcomes the detection performance reduction caused by monocular vision imaging anger difference,effectively.
