Abstract

Methods and a device for updating a track of an object in relation to a current image frame are disclosed. A first track of an object in a sequence of image frames preceding the current image frame is determined using a first computer implemented tracker. The first tracker is updated in at least a first subset of image frames of the sequence of image frames based on an object detection from a computer implemented object detector using an object detection algorithm. The first track includes a respective estimated location of the object in each image frame of the first subset of image frames of the sequence of image frames. A location of the object in the current image frame is predicted using a motion model of the first tracker, and determined respective locations of detected motion areas in the current image frame are received from a computer implemented motion detector using a motion detection algorithm. Using the first tracker, and based on the predicted location of the object in the current image frame and the determined respective locations of the detected motion areas, it is determined that a detected motion area of the detected motion areas is associated with the object in the current image frame. The predicted location of the object in the current image frame is updated using the first tracker and based on the determined location of the detected motion area determined to be associated with the object in the current image frame. Thereby an estimated location of the object in the current image frame is determined.
