In this paper, a novel global abnormal event detection algorithm is proposed for multiple disjoint synchronous camera network. We treat detecting unusual global events as discovering context-incoherent patterns through learning temporal dependencies between distributed local activities observed within and across camera views. Trajectories are firstly extracted using mean-shift approach in each camera...
As one of the newest technology, LTE has become increasingly popular after GSM and UMTS. As the LTE industrial chain matures and user requirements grow, E-UTRAN will be deployed on a large scale, covering all urban areas and most other regions. The control plane, which is responsible for connection management, mobility and security, has aroused more and more attention. In order to have an in-depth...
Driver fatigue and sleep deprivation have been widely recognized as critical safety issues that cut across all modes in the transportation industry. FMCSA, the trucking industry, highway safety advocates, and transportation researchers have all identified driver fatigue as a high-priority commercial vehicle safety issue. There has been much research work done in driver fatigue detection. This paper...
An efficient communication protocol is a foundation of Cluster system's communication networks. In this paper, an underlying communication protocol which provides a shared buffer communication for interconnection system whose CPUS are connected by the Hyper Transport bus is proposed. The experiments show that the proposed shared buffer communication method is far more efficient than that adopts Ethernet...
During the production of oilfield, it is necessary to understand the strata pressure in the recovery process, which is the so-called current formation pressure. However, how to choose the pressure monitoring well point correctly is one of the important tasks in the oilfield development. Usually the simplest method of understanding the strata pressure is actual measurement, but in order to get the...
Driving fatigue detection is a key technique in vehicle active safety. In this paper, a practical driver fatigue detection algorithm is proposed, it employs sequential detection and temporal tracking to detect human face, which combines the superiorities of both Adaboost and mean-shift algorithm; a morphologic filter method is given to localize the pair of eyes in the detected face area. Then multiple...
