基于光流约束自编码器的动作识别
Action recognition based on optical flow constrained auto-encoder
摘要
Abstract
To improve the capability of feature learning in extracting motion information such as amplitudes and directions and to increase the recognition accuracy, an optical flow constrained auto-encoder is proposed to learn action features.The optical flow constrained auto-encoder is an unsupervised feature learning algorithm based on single layer regularized auto-encoder.The algorithm uses the neural network to reconstruct the video pixels and use the corresponding optical flows in video blocks as a revised regularization.The neural network learns the appearances of the action and encodes the motion information simultaneously.The associated codes are used as the final action features.The experimental results on several well-known benchmark datasets show that the optical flow constrained auto-encoder can detect the motion parts efficiently.On the same recognition framework, the proposed algorithm outperforms the state-of-the-art single layer action feature learning algorithms.关键词
