Method and device for tracking an object in a sequence of images

摘要

The method involves determining an object window in an image recorded at a time period using an object-tracer (14). The image of an image sequence is converted into an integral image, and a search window is formed in the image. A set of responses of pattern application in the image content of the search window are calculated for each search window. The set of responses of the search window in the image are compared with a set of responses of the object window in the image that is recorded at another time period or that is recorded at a starting time period for tracing an object. An independent claim is also included for a device for tracing an object in an image sequence.
