While for static cameras several background subtraction approaches have
been developed in the past, for non-static pan/tilt cameras efficient and
robust motion detection is still a challenging task. Known approaches use
image-to-image registration methods to generate a panorama background model
of the scene, which spans a joint pixel coordinate system for later
background estimation and subtraction. However, for a real-time
panorama-based background subtraction a highly efficient image-to-panorama
registration is needed. For this purpose, in this paper a key-frame
representation of the panorama image is proposed and a strategy for fast
global homography estimation in large panorama images is presented.
