Removing Temporal Stationary Blur in Route Panoramas

The route panorama is a continuous, compact and complete image representation of scenes along a route. It is generated continuously from reading a preset line in a camera frame that moves along a smooth path. More complicated than the mathematical model of slit scanning, the physical width of a sampling line may yield a temporal blur, named stationary blur, in the route panorama. It is the counterpart of the motion blur and appears at distant scenes. We analyze the sampling of the route panorama, and recover the intrinsic high frequency components from spatio-temporal slit data. The sharpened results enhance the cityscapes archiving and visualization in virtual tour and navigation
