This chapter describes an original contribute of this book: a method to solve the correspondence problem in multi-camera systems without the assumption of epipolar geometry. This method is suitable to reduce the sensory gap and the problem of the presence of mutual occlusions among moving objects inside a scene. Using this method it is possible to improve the performance of the tracking algorithm. The chapter starts with a brief problem overview and then it presents a description of the epipolar geometry. Finally the proposed solution is described and the final considerations are reported.
