Method for automatic detection and tracking of multiple objects
摘要
A method for automatically detecting and tracking objects in a scene. The method acquires video frames from a video camera; extracts discriminative features from the video frames; detects changes in the extracted features using background subtraction to produce a change map; uses the change map to use a hypothesis to estimate of an approximate number of people along with uncertainty in user specified locations; and using the estimate, track people and update the hypotheses for a refinement of the estimation of people count and location.
