Human Action Recognition Based On Self-Learning Feature And Hmm, Jiarui Wen, Lina Liu, Rui Ling, Shiwei Ma

Journal of System Simulation

Abstract: The current methods of human action recognition by computer vision are mostly based on hand-craft features and usually prior knowledge-required. They inevitably depend on specific applications and neglect the inner structure of visional information. A novel method which integrated self-learned pose features and combined posture symbol rules was proposed to achieve the recognition of human action more efficiently. The structural features of posture silhouette were extracted and a codebook of primary posture was built through the establishment of a sparse auto-encoder network. Then, in the phase of recognition, the Hidden Markov Model was employed to train the models …

Group-Based Image Compositing In Heterogeneous Environments, Liu Ning, Dengming Zhu, Zhaoqi Wang, Wei Yi

Journal of System Simulation

Abstract: Image compositing requires dense inter-node communications and could easily become the bottleneck of a parallel visualization system. Conventional image compositing algorithms assume the environment is homogeneous and take no heterogeneity into consideration. In a heterogeneous environment, this assumption is likely to cause unreasonable load distribution among the nodes. To address this problem, we present a group-based image compositing algorithm in heterogeneous environments. It is able to distribute the workloads among the nodes according to computing and networking characteristics of the heterogeneous environments. We conduct a comprehensive evaluation on the ns-3 network simulator. Experiment results shows that when the environment …
