Abstract
A detection system fusing motion detection and object detection for various applications such as tracking, identification, and so forth. In an application framework, model information may be developed and used to reduce the false alarm rate. With a background model, motion likelihood for each pixel, for instance, of a surveillance image, may be acquired. With a target model, object likelihood for each pixel of the image may also be acquired. By joining these two likelihood distributions, detection accuracy may be significantly improved over the use of just one likelihood distribution for detection in applications such as tracking.

7. A method for fusing detection techniques, comprising:
-
acquiring images of an area of surveillance;
extracting background from the images to obtain foreground;
determining foreground according to motion of a blob;
compiling a model having features characteristic for a category of an object in the area of surveillance;
detecting an object from the images according to similarity of features of the object with the features of the model; and
fusing the motion of the blob with the detecting of the object to form a hypothesis of a target. - View Dependent Claims (8, 9, 10)
