The present invention is directed to a system and method for tracking objects, such as customers in a retail environment. The invention is divided into two distinct software subsystems, the Customer Tracking system and the Track Analysis system. The Customer Tracking System tracks individuals through multiple cameras and reports various types of information regarding the tracking function, such as location by time and real world coordinates. The Track Analysis system converts individual tracks to reportable actions. Inputs to the Customer Tracking System are a set of analog or digital cameras that are positioned to view some physical environment. The output of the Customer Tracking System is a set of customer tracks that contain time and position information that describe the path that an individual took through the environment being monitored. The Track Analysis System reads the set of customer tracks produced by the tracking system and interprets the activities of individuals based on user defined regions of interest (ROI). Examples of a region of interest are: (1) a teller station in a bank branch, (2) a check-out lane in a retail store, (3) an aisle in a retail store, and the like.

A method and system for tracing profiling information using per thread metric variables with reused kernel threads is disclosed. In one embodiment kernel thread level metrics are stored by the operating system kernel. A profiler request metric information for the operating system kernel in response to an event. After the kernel thread level metrics are read by the operating system for a profiler, their values are reset to zero by the operating system kernel. The profiler then applies the metric values to base metric values to appropriate Java threads that are stored in nodes in a tree structure base on the type of event and whether or not the kernel thread has been reused. In another embodiment non-zero values of thread level metrics are entered on a liked list. In response to a request from a profiler, the operating system kernel reads each kernel thread's entry in the linked list and zeros each entry. The profiler can then update the intermediate full tree snapshots of profiling information with the collection of non-zero metric variables.
