Abstract

A method for tracking an object in a plurality of frames includes obtaining a contour of an object in a frame. For each remaining frame among the plurality of frames, the following steps are performed. A probability map generator generates a plurality of probability maps containing probability values for one or more pixels for a current frame. A contour is estimated for the current frame based on the plurality of probability maps. User input is obtained for refining the estimated contour. Based on the user input, one or more local regions to be added and/or removed are identified and recorded in a local region list. The local region list is maintained and updated during the tracking process and is used together with the probability map generator.
