    摘要: A system for classifying image data includes a vision system (58) for continuously imaging an area (42) of interest and providing an image signals. A classifier (84) determines an image class corresponding to each image signal, determines a confidence level for each determined image class, determines a time period for the confidence level, and establishes an image classification in response thereto. Switching between image classifications is in response to the confidence level and time period of the confidence level. When used in a vehicle restraining system (20), other monitor vehicle parameters (54) can be used to adjust the confidence levels and time periods needed to switch between image classifications.

    摘要: An apparatus (100) for tracking at least one head candidate comprises an image analyzer (104) for analyzing an image signal to identify at least one of a possible plurality of new head candidates within an area of interest. The image analyzer (104) provides data regarding the identified head candidates. A tracking system (108) stores location information for at least one tracked head candidate. A candidate matcher (106) predicts the current position of a given tracked head candidate and selects a subset of the at least one of a plurality of new head candidates according to their distance from the predicted position. The similarity of each member of the selected subset to the tracked candidate is evaluated to determine if a member of the selected subset represents a current position of the tracked candidate.
