基于多特征融合的动作识别方法
Multi-feature-fusion based human action recognition method
摘要
Abstract
This paper proposed a novel action recognition method based on multi-feature fusion.In this method,the spatial-temporal features and depth features were merged in a random forest framework.The human body joint coordinates obtained from depth image sequences were processed into displacement feature and part-center feature as two new depth features.We applied these two depth features to describe the three-dimension structure of human.We densely sampled the trajectories from RGB image sequences,and utilized the foreground detection approach to reduce the effect of complex background.Then spatial-temporal features were constructed by the Bag-of-Words model with trajectories from the foreground.Finally,the robust random forest framework fused both the spatial-temporal features and the depth features for recognizing human actions in RGB-D image sequences.Experimental results on MSR Daily Activity 3D dataset demonstrated the effectiveness of the proposed method.关键词
