Abstract
The problem of establishing trajectories of objects in a long
image sequence is addressed, in the case of occlusion, disocclusion of
objects, and crossing trajectories and junctions. Two complementary
criteria are investigated in order to arrive at the decision of linking
two partial pieces of trajectory which could come from a single object
in motion, i.e., the continuity of the global trajectory, and the
continuity of the velocity of the moving object. Experiments are
conducted on long sequences of real images. Complete trajectories are
successfully recovered
