Common use of BACKGROUND EXTRACTION MODULE Clause in Contracts

BACKGROUND EXTRACTION MODULE. To run properly, the VVDC system requires a good quality background, at least at the virtual detector locations. The background extraction module used in the VVDC system employs the median background-extraction method described in Section 5.1. Depending on the roadway condition, it may take up to a minute to run the algorithm. To display the background extraction process visually to users, the module employs a task bar. Figure 6-5 shows a snapshot taken in the middle of a background extraction process. The green portion of the lower right bar indicates the percentage of the background extraction task completed.
