Abstract
A method of tracking an object in a sequence of panoramic images and an apparatus and a computer program code suitable for implementing the method are described. For obtaining a current position of an object in a current panoramic image of a sequence of panoramic images, first an initial 2D position of the object in a preceding panoramic image is obtained. The initial 2D position is then projected back into 3D space to obtain an initial 3D position. Then a set of candidate 3D motion vectors is obtained based on the initial 3D position. The initial 3D position is subsequently motion compensated using this set of candidate 3D motion vectors to obtain a set of motion compensated 3D positions. The motion compensated 3D positions are then projected into a set of candidate 2D positions.
