Probabilistically Tracking System Calls
نویسندگان
چکیده
Monitoring system calls made by an application is useful for debugging, for diagnostics as well as for security applications. Existing tools for monitoring system calls either suffer from a large runtime overhead, or require root permission to change the kernel of the operating system. We propose an approach that tackles both of these issues. We implemented a tool that runs completely in user space and requires no change to the operating system. It works by probabilistically sampling a few of the system calls made a process, thus lowering its overhead. We show that by using proper sampling techniques, our tool is able to figure out the same information as a tool that tracks all system calls.

متن کاملOcclusion robust Tracking Ofmultiple Objects
This paper focuses on the problem of vision-based tracking of multiple objects. Probabilistic tracking in 3D supported by multiple video streams allows us to formalize an efficient observation model that is robust to occlusions. Each tracked object is assigned a support layer, a probabilistically meaningful pixel occupancy map, supplying weights used in the calculation of other objects observat...

Vehicular networks have attracted significant attention in the context of traffic control and management applications. However, vehicular networks also have important applications in crime prevention and criminal investigations. This paper presents a system for passively tracking a target vehicle whose driver is assumed to be a “person of interest.” The tracking system relies on the dynamic rec...

in Proc. of Asian Conference on Computer Vision (ACCV), 2004 Sensor fusion for object tracking has become an active research direction during the past few years. But how to do it in a robust and principled way is still an open problem. In this paper, we propose a new fusion framework that combines both the bottom-up and top-down approaches to probabilistically fuse multiple sensing modalities. ...

One of the main problems in wind energy conversion system (WECS) is how to achieve maximum output power in different wind speeds. Maximum methods for maximum power point tracking in wind energy conversion systems require the knowledge of system characteristics and mechanic sensors. So, using these methods practically will follow with high price and an abundant difficulties. In this pape...
